Validation

In this section we provide information about the benchmarks and tests that we have done to validate GEOS-Chem v11-02.

1-month and 1-year benchmarks

For complete information about the benchmark simulations used to validate GEOS-Chem v11-02, please see our GEOS-Chem v11-02 benchmark history wiki page.

Unit tests for GEOS-Chem v11-02

We perform a full set of unit tests on GEOS-Chem on an almost daily basis. These tests ensure that each new feature being added does not break any existing functionality.

Here are the unit tests that we ran before submitting 1-month benchmark simulation for v11-02. Click on the links below to see the results from each set of unit tests:

Previous issues now resolved in GEOS-Chem v11-02

The following bugs and/or technical issues have been resolved in v11-02.

Removed the NNPAR parameter from CMN_SIZE_mod.F

This update was included in v11-02a and approved on 12 May 2017.

The NNPAR parameter is a holdover from when we used COMMON blocks to store GEOS-Chem arrays. With the advent of the GEOS-Chem species database, we now use State_Chm%nSpecies to represent the total number of species in the chemistry mechanism, and State_Chm%nAdvect to represent the total number of advected species.

We have therefore removed the following lines (in RED) from CMN_SIZE_mod.F:

      !=================================================================
      ! TRACER & EMISSION SPECIES PARAMETERS
      !
      ! NNPAR   = max number of tracers
      ! NEMPARA = max number of anthropogenic emission species
      ! NEMPARB = max number of biogenic      emission species
      !=================================================================
      ! increase NNPAR and NEMPARA an extra amount (hotp 7/31/09)
#if   defined( TOMAS )
# if    defined( TOMAS40 )
      INTEGER,    PARAMETER :: NNPAR   = 430   ! For TOMAS40 (sfarina 6/11/13)
# elif  defined( TOMAS15 )
      INTEGER,    PARAMETER :: NNPAR   = 205   ! For TOMAS15 (sfarina 6/11/13)
# elif  defined( TOMAS12 )
      INTEGER,    PARAMETER :: NNPAR   = 178   ! For TOMAS12 (sfarina 6/11/13)
# else
      INTEGER,    PARAMETER :: NNPAR   = 340   ! For TOMAS (win, bmy, sfarina 6/11/13)f
# endif
#else
      INTEGER,    PARAMETER :: NNPAR   = 150   ! For non-TOMAS simulations
#endif

Print the version number to the log file

This update was included in v11-02a and approved on 12 May 2017.

In routine DISPLAY_GRID_AND_MODEL of GeosCore/main.F, we now print out the version number, e.g.

Using GEOS-Chem version: v11-02

to the log file (i.e. stdout output stream). This will facilitate debugging.

Include TOA pressure when calculating dry pressure edges

This fix was included in v11-02a and approved on 12 May 2017.

For physicality and consistency with GCHP, the top-of-atmosphere (TOA) pressure is now included when calculating dry pressure edges. The following lines in GeosCore/dao_mod.F were changed from:

     ! Reset dry surface pressure to zero
     PS_DRY = 0.0e+0_fp

to:

     ! Reset dry surface pressure to TOA value
     PS_DRY = GET_AP(LLPAR+1)

ND26 vertical flux diagnostic does not yield mass balance in advection

This update was included in v11-02b and approved on 16 Jun 2017.

To achieve mass balance in the advection diagnostic output (ND24, ND25, and ND26) Ilya Stanevic (U. Toronto) suggested that the FZ array be used to compute the ND26 vertical mass flux diagnostic for all levels. This is similar to how FX is used for ND24 and FY for ND25. Note that this fix is only for global advection since the FZ array is not defined for the nested model. With this update, the global ND26 vertical flux diagnostic is defined as the flux into the grid box above (e.g. ND26(:,:,1) is flux from level 1 to level 2 and ND26(:,:,LLPAR) is all zeros).

ND40 planeflight diagnostic not always written out when turned on

This update was included in v11-02b and approved on 16 Jun 2017.

We have moved the discussion of this issue to our Planeflight diagnostics wiki page.

CO2 emissions unit conversion not consistent with new advection pressure

This update was included in v11-02b and approved on 16 Jun 2017.

We have moved the discussion of this issue to our CO2 simulation wiki page.

Fixed an incorrect format statement in input_mod.F

This update was included in v11-02c and approved on 21 Sep 2017.

Chris Holmes wrote:

An incorrect format specification caused GEOS-Chem to crash rather than write a helpful error message when the transport timestep is too big. The code in RED was removed and the lines in GREEN was added at approximately line 3324 of input_mod.F.

With the 20 minute time steps recommended in v11-01, Diag50 gets written and overwritten multiple times in the first hour of every day! The fix is simply to have this function return TRUE if the GMT time is 00:00.
2. Within WRITE_DIAG50 there is the following block of code

        ! Pick the proper divisor, depending on whether or not the
        ! species in question is archived only each chem timestep
        SELECT CASE ( ND50_TRACERS(W) )
           CASE (91, 92, 76, 77 )
              DIVISOR = COUNT_CHEM3D
           CASE DEFAULT
              DIVISOR = COUNT
        END SELECT

I see nothing special about tracers 76, 77, 91, and 92 that should make them divided by a different number. The special tracers numbers are all >= 150 for ND50. I suspect this is left over from a previous code revision. I think it should be DIVISOR=COUNT for all ND50_Tracers.

Add MERRA2 to #if and #elif statements where it had been omitted

This update was included in v11-02c and approved on 21 Sep 2017.

In v11-02, (commit 8d27b9a), I am trying to unify defined( GEOS_FP ) and defined( MERRA ) by a adding a new tag defined( FlexGrid ). However, I find some model codes that treat them differently without explanation:

(1) In GeosCore/convection_mod.F: At the #if statement at line 1443, MERRA2 will execute the #else block. But it should execute the #if block:

(3) At line 1193 of GeosCore/hcoi_gc_main_mod.F90, I noticed what appears to be a typo:

      #if defined ( GEOS_FP ) || ( MERRA2 )

(4) At line 779 of GeosCore/land_mercury_mod.F, I noticed this #if block, which could be written better:

               FIRSTTIME = .FALSE.

I have a few housekeeping suggestions that I think would be helpful to GC users.

Combine all of the timestep settings in input.geos in a single “Timesteps” menu. With the default timesteps being much shorter now, there seems to be much more interest in changing these timesteps (e.g. do model development with large time steps, then publication runs with small time steps), myself included. It would be nice to change all of the time steps in one place. Besides making it easier to double or halve them all, a single menu would also help clarify whether the time steps for each process have the recommended 1:2 ratio for operator splitting.
Move all of the photolysis and aerosol optics data files out of the run directory and into a folder in ExtData. That would allow them to be documented, tracked and updated like emissions. As far as I have seen, these files are rarely modified by users, so they don’t need to be in the run directory. That would include the following files...

      brc.dat
      dust.dat
      FJX_j2j.dat
      FJX_spec.dat

Update CH4 latitude bands for 2014-2016

This update was included in v11-02d (approved 12 Feb 2018).

The last year of latitudinal CH4 concentration data (based on CMDL flask observations) was 2013. (Data is provided in 4 latitude bands: 90°S-30°S, 30°S-0°N:, 0°N-30°N, 30°N-90°N.) Katherine Travis has updated the subroutine get_global_ch4.F with additional years of latitudinal CH4 data from 2014 thru 2016.

Lee Murray will provide additional latitudinal CH4 concentration data through present day, once it is available. See this post on our NOx-Ox-HC-aerosol wiki page for more information.

Add bug fixes for GLYX, MGLY, IEPOX, and IMAE heterogeneous chemistry added in v11-02c

This update was included in v11-02d (approved 12 Feb 2018).

Sebastian Eastham wrote:

There’s a bug in the v11-02c het rate code. In KPP/Standard/gckpp_HetRates.F90, many of the dedicated routines (e.g. HetIMAE) loop over NAERO. The loop looks like

   Do N=1,NAERO
      ! [Comment]
      If (N==8) Then
         XSTKCF = [number] 
      End If
      If (N == 13) Then
         ADJUSTEDRATE = XAREA(N)*XSTKCF
      Else
         ADJUSTEDRATE = ARSL1K( XAREA(N), XRADI(N), XDENA, XSTKCF, XTEMP, (A**0.5_FP) )
      End If
      Het_IMAE = Het_IMAE + ADJUSTEDRATE
   End Do

The problem here is that every aerosol after aerosol 8 is inheriting the sticking coefficient from aerosol 8. Crucially, this includes SOAS – so the fact that the simple SOA tracer is missing could affect this. GCC is artificially increasing the het rate on all aerosols because of this bug, whereas GCHP is not. Fixing this would be as simple as inserting either XSTKCF = 0.0 or XSTKCF = B at the start of the loop, where I’ve written ! [Comment]. The question of which is correct is really a science question (probably XSTKCF = B, although I’d ask the original authors). However, what’s definitely true is that one of these two options needs to be put in or the result of the calculation will be wrong.

Fixing this bug is likely to change SOA burdens in both GCC and GCHP. In gckpp_HetRates, the following routines are definitely affected:

HetGLYX
HetMGLY
HetIEPOX (forms SOAIE)
HetIMAE (forms SOAME)

The other het routines look like they have the correct form (either by a "header" of XSTKCF = B, or because they have an If...ElseIf...Else...End clause that catches all possible values of N and sets XSTKCF accordingly).

The solution is to set XSTKCF = TINY(1e0) where ! [Comment] is in the code snippet above, following what is done in Eloise Marais's version of calcrate.F.

Add fix for IPMN reactions contributing to high P(Ox) and L(Ox)

This update was included in v11-02d (approved 12 Feb 2018).

During the 1-year benchmark for v11-02d, Lu Hu pointed out an issue in the O3 budget where P(Ox) and L(Ox) were too high (~40000 Tg/yr compared to the expected 4000-5000 Tg/yr). This issue was tracked to the following reactions in the chemical mechanism:

IMAO3 + NO2 {+M} = IPMN  # Impacts L(Ox)
IPMN = IMAO3 + NO2       # Impacts P(Ox)

Eloise Marais wrote:

Remove support for GCAP, GEOS-4, MERRA, GEOS-5

This update was included in v11-02d (approved 12 Feb 2018).

Daniel Jacob wrote to the GEOS-Chem Steering Committee:

I met today with the GCST and they brought up again the issue of discontinuing support for old met fields (GEOS-4, GEOS-5, MERRA) in GEOS-Chem. They told me that it would benefit the code structurally to stop supporting these old met fields, also that GCHP will not be able to use them since the data are in binary format. We would also reclaim some disk storage, and we would satisfy GMAO who doesn’t like that we’re using these old met fields.

We will discontinue support for the old met fields (MERRA, GEOS-4, GEOS-5) in future model versions BUT we will keep the data archives [at Dalhousie] at least for now.

Loretta Mickley consulted with Lee Murray, Amos Tai, and Jeff Geddes of the Chemistry-Ecosystems-Climate Working Group and wrote:

It looks like we can safely retire the GCAP met fields and #ifdef GCAP sections of the code now. As Lee describes, there are other capabilities in use by the chemistry-climate community that we will eventually implement into standard code.

I believe we currently have GCAP2 met fields stored at Harvard, and these should be maintained. GCAP2 consists of met fields from the GISS ModelE2.1 present-day and future. Lee Murray and Eric Leibensperger created these files, after a lot of work!

Remove MONX from chemical mechanisms

This update was included in v11-02e (approved 24 Mar 2018).

Sam Silva (MIT) wrote:

I was wondering why there were three monoterpene species in the chemical mechanism: MTPA (lumped alpha pinene), LIMO (lumped limonene) and then MONX (all monoterpenes).

MONX doesn’t play with any of the monoterpene nitrate chemistry, it just is converted into 3 formaldehyde:

   MONX = 3.000CH2O :                          GCARR(1.07E-05, 0.0E+00, 0.0);

It seems like having the MONX group (all monoterpenes) and the speciated lumped monoterpenes is an inconsistency. Ultimately, I’m interested in adding Glyoxal formation from monoterpenes, and it’s not clear to me how to properly do that, given the three different species.

Do you know of a reason why MONX is still in the mechanism?

Melissa Sulprizio responded:

I had a look through the Git history of the globchem.dat file. The MONX -> 3CH2O reaction was originally included in the SOA mechanism. Just prior to the v10-01 public release, the GEOS-Chem Steering Committee requested that we include SOA chemistry in the benchmark simulations. At that time, MONX was made an active species and the MONX -> 3CH2O reaction was added to the globchem.dat file for the benchmark simulations. No other monoterpene chemistry was included in that chemical mechanism at the time.

In v11-02a, we introduced monoterpene chemistry during Emily’s PAN updates. At that time MTPA was introduced. The monoterpene chemistry was further modified and expanded upon in v11-02c following Jenny’s updates originally made for SEAC4RS.

Looking back at Emily’s original PAN updates that she sent to us (based on v9-02h), it looks like MONX is a dead species in globchem.dat and the MONX -> 3CH2O reaction is not included. That may have been an oversight during the PAN updates implementation. Since Emily’s globchem.dat did not include the SOA chemistry by default and our standard/benchmark mechanism did, it wasn’t clear that we should remove the MONX species and reaction.

The MONX species will be removed from GEOS-Chem mechanisms in v11-02e, upon the recommendation given to us by Emily Fischer. This update also requires the addition of the MTPO species to represents all the monoterpenes not covered by species MTPA. See this post on our Secondary organic aerosols wiki page for more details.

Change timestep units from minutes to seconds

Andrea Molod (GMAO) wrote:

As part of the side by side testing of GMI and GEOSChem chemistry in our coupled framework, we have run across a small but annoying issue. The "annoyance" is that the geoschem code does not accomodate a call at a time step that is not a multiple of a minute. our current model "heartbeat" is 450 seconds (for many reasons) at what is now a wide range of resolutions, and we end up having to run with geoschem at 300 seconds (for other reasons internal to GEOS).

To address this issue, the timestep duration specifications in the configuration file input.geos will be changed from minutes to seconds. The data type will stay as integer. This change has implications for the GEOS-Chem source code. Subroutines of form GET_TS_{component} now return seconds instead of minutes and usages of time units since a reference time must incorporate seconds as well as minutes in the calculation.

Fixes for two new ND21 binary diagnostics introduced in v11-02

This update was included in v11-02e (approved 24 Mar 2018).

Two new ND21 diagnostics introduced in v11-02c are assigned to the wrong tracer numbers in the AD21 array written to binary output. The optical depth of SOA from aqueous isoprene is written to tracer 34 but should be written to tracer 58. The aqueous aerosol volume is written to tracer 35 but should be written to tracer 59.

These tracer number errors resulted in an inconsistency with metadata supplied by GAMAP and prevented the diagnostics from being written to file during a full chemistry simulation. The new diagnostics also overwrite the dust AOD wavelength 2 diagnostics for bins 2 and 3 if run with RRTMG. A parallelization issue in setting one of the diagnostics is also present.

To get around these issues in v11-02c and v11-02d, replace AD21 index 34 with 58 and 35 with 59 where the diagnostics are set in aerosol_mod.F and declare local variable TAERVOL as private in the OMP loop in subroutine RDAER.

Use spun-up restart file to initialize benchmark simulations

This update was included in v11-02e (approved 24 Mar 2018).

Starting in GEOS-Chem v11-02e, we have replaced the default restart file (initial_GEOSChem_rst.4x5_standard.nc) used to initialize 1-month benchmark simulations and UCX-based simulations in general. The previous default restart file had not been spun up in many years, so several species concentrations did not reflect updates to the model. The new restart file was obtained from the 1-year benchmark v11-02d-Run2 and has been spun up for many years. The updated restart file also allowed us to remove the initial stratospheric 2D mixing ratio option from input.geos and use the values provided by the restart file to initialize species concentrations for the relevant UCX species.

Restore use of prod/loss rates from GMI in the mesosphere for UCX-based simulations

This update was included in v11-02f (approved 17 May 2018).

Following the implementation of the prod/loss rates from UCX in v11-02e, it was discovered that we need to restore the use of prod/loss rates from GMI in the mesosphere for UCX-based simulations. The prod/loss rates saved out from a UCX simulation via KPP are only saved out on 59 levels (i.e. the maximum number of levels in the chemistry grid). Values in levels 59-72 (~1 hPa to ~ 0.01 hPa according to our vertical grids wiki page) are set to zero.

Chris Holmes wrote:

I think it’s important to do some kind of mesospheric P/L in the UCX simulations. If we’re going to have a stratospheric chemistry capability in GEOS-Chem, we need to have a reasonable upper boundary condition (and zero P/L in the mesosphere is not reasonable). It seems to me that the easiest thing is to retain the GMI P/L in the mesosphere in UCX simulations.

Sebastian Eastham wrote:

I think that's the most sensible approach for now. One additional point that's worth raising is that, in the course of the evaluation of the UCX by the GMI group, they actually ended up extending the UCX up into the mesosphere. This removed the need for any mesospheric paramaterizations, and did not involve adding any new chemistry or code. They found that this gave the same results as the GMI model - no big surprise since the GMI and UCX models are very similar, and the GMI model is already run up to the model top. As a result we may want to consider (in v11-03) adding an "extended UCX" option which runs UCX directly up to the model top which will resolve this problem when generating P/L data. It will also allow interested users to avoid reading in all the P/L data (a not-insignificant startup cost) or using mesospheric paramaterizations.

Fix bug in units of UCX P/L rates

This update was included in v11-02f (approved 17 May 2018).

Christoph Keller wrote:

I think I found a bug in the implementation of the UCX P/L rates: in subroutine Set_PLVEC (in strat_chem_mod.F90), there is a unit conversion of the UCX P/L fields (from molec/cm3/s to v/v/s and 1/s, respectively), which will be erased after the first simulation month because the arrays in the PLVEC(:) structure are only *pointers* to the 3D fields managed by HEMCO (PLVEC(N)%PROD and PLVEC(N)%LOSS). After the first simulation month, HEMCO automatically updates the UCX P/L arrays (because they change monthly), thus overwriting the unit conversion performed in Set_PLVEC. So I'd expect the first month to be ok but then after the second month, GEOS-Chem will actually apply UCX P/L loss rates that are in molec/cm3/s instead of v/v/s and 1/s.

In short, the arrays in PLVEC (PLVEC(N)%PROD and PLVEC(N)%LOSS) should not be modified because HEMCO changes them automatically.

The solution for this issue is to apply the unit conversion to the prod/loss rates at the time that we copy them into the loss frequency (k) and production term (P) variables in routine DO_STRAT_CHEM.

    GEIA_NH3_BIOF $ROOT/NH3/v2014-07/NH3_biofuel.geos.4x5.nc NH3_BIOFUEL 1998/1-12/1/ C xy  kg/m2/s NH3 - 2 1
    GEIA_NH3_NATU $ROOT/NH3/v2014-07/NH3_geos.4x5.nc         NH3_NATU    1990/1-12/1/ C xy  kg/m2/s NH3 - 3 1

The standard HEMCO_Config.rc file uses the 4x5 degree resolution emission files (NH3_biofuel.geos.4x5.nc and NH3_geos.4x5.nc) although there are files at 1x1 degree resolution in the same directory (NH3_biofuel.geos.1x1.nc and NH3_geos.1x1.nc). We were wondering why the default setting is to use the 4x5 degree resolution rather than the 1x1 degree resolution? It looks like the original GEIA NH3 emissions are at 1x1 degree resolution.

There are large differences between the files at different resolutions. Attached are some plots of the NH3 natural emissions for the three resolutions of files in the $ROOT/NH3/v2014-07 folder. When we calculate the total global burden, the 1x1 degree emissions give a total of ~26 Tg NH3 yr-1 which is relatively similar to the Park et al. Transboundary Pollution paper which quotes 20 Tg N yr-1 global natural ammonia emissions. The 4x5 degree emissions are a factor of 20 lower than this and we wondered whether perhaps there was an error in the re-gridding from 1x1 degree to 4x5 degree?

When we run our simulation using the default 4x5 degree emissions, the modelled ammonia concentrations are too low compared to observations, whereas when we run with the 1x1 degree resolution emissions we get much better agreement.

We just wanted to know whether there was a reason that 4x5 is used as the standard emissions instead of 1x1 degree, and if not whether the HEMCO_Config.rc file might need updating to use the 1x1 degree emissions instead?

Bob Yantosca wrote:

I am not 100% sure why we still use the GEIA NH3 emissions at 4x5 in the HEMCO. It may have been that while we were developing HEMCO, we needed to keep those NH3 emissions at 4x5 in order to better match the emissions in the pre-HEMCO code, so that we could get “apples-to-apples” comparisions. It could have been as simple as that. I would recommend bringing this to the attention of the Emissions and Deposition Working Group.

Eloise Marais wrote:

GCST, in summary, can we use the GEIA natural NH3 emissions file at 1x1 resolution rather than 4x5? Currently the default is 4x5 and Eleanor from U York found large differences between these two files, where the 1x1 emissions are more consistent with observations. It looks like GEIA natural NH3 will eventually be retired and replaced with emissions that Amos Tai is working on, so this would be an interim fix.

NOTE: The 1-year benchmark v11-02f-Run0 showed that the 1° x 1° NH3 emissions file was problematic, producing 20X too much emissions as expected. This is probably due to a regridding issue. We have since removed this update from the v11-02-release-candidate version and this issue remains open. (Bob Y., 07 Jun 2018).

GEIA anthro and biofuel NH3 are skipped if either CEDS or EDGARv43 is used

The GCST has confirmed that HEMCO's default behavior is to skip the following GEIA anthropogenic (GEIA_NH3_ANTH) and biofuel (GEIA_NH3_BIOF) if either the CEDS or EDGARv43 is selected as the global inventory. This is because these GEIA emissions are listed in the HEMCO_Config.rc files with a lower priority than CEDS or EDGARv43.

The GEIA NH3 natural emissions (GEIA_NH3_NATU) and emissions from arctic seabirds (SEABIRD_NH3) will always be read, regardless of the choice of global base inventory.

Fix for organic nitrate chemistry

This update was included in v11-02f (approved 17 May 2018).

Xuan Wang wrote:

For MONIT and HONIT = INDOL + HNO3, I see from wiki we should use uptake rate of 2.78e-04 s-1 (lifetime = 1hour). However, we are setting gamma = 2.78e-04 s-1, not the uptake rate. I change it to manually setting the rate to 2.78e-04 s-1.

Jenny Fisher wrote:

In my version there were 3 gas-phase monoterpene nitrate species (MONITU, MONITS, HONIT) and one monoterpene nitrate aerosol species (let’s call it pONITm since it had a confusing name in my code), plus INDIOL.

In my version, for each gas phase species we had e.g. MONITU -> pONITm with gamma = 0.01

Then pONITm -> HNO3 + INDIOL with a lifetime of 1 hour (set as a simple first order rate constant, not as an uptake rate).

Xuan Wang wrote:

In v11-02, your pONITm seems to be IONITA and MONITA. For each gas it is like MONITU = MONITA with gamma = 0.01. For MONITA/IONITA =HNO3 + INDIOL, it is like this:

        ! Define gamma for MONITA 
        ! Imposed lifetime = 1 hour (Fisher et al., 2016)
        XSTKCF = 2.78e-4_fp

And later:

        ! Reaction rate for surface of aerosol
        ADJUSTEDRATE=ARSL1K(XAREA(N),XRADI(N),XDENA,XSTKCF,XTEMP, &
                              (A**0.5_FP))

Jenny Fisher wrote:

Ok, this does seem like an error I think, although I don’t really know how to fix it in the framework of v11-02. Should we even be using XSTKCF at all? Is there a way to do this in the v11-02 chemistry framework to just set the rate constant to 2.78e-4 s^-1?

Melissa Sulprizio wrote:

If you would like to just set the rate constant for this reaction to 2.78e-4 then we can change it from a heterogeneous reaction in the .eqn files (i.e. utilizing the HET function in gckpp_HetRates.F90) to a standard reaction utilizing the Arrhenius equation (i.e. function GCARR). For example:

    IONITA = INDIOL + HNO3 :  HET(ind_IONITA,1);  {2017/07/14; Fisher2016; KRT,JAF,CCM,EAM,KHB,RHS}
    MONITA = INDIOL + HNO3 :  HET(ind_MONITA,1);  {2017/07/14; Fisher2016; KRT,JAF,CCM,EAM,KHB,RHS}

becomes

    IONITA = INDIOL + HNO3 :  GCARR(2.78E-04, 0.0E+00, 0.0);  {2017/07/14; Fisher2016; KRT,JAF,CCM,EAM,KHB,RHS}
    MONITA = INDIOL + HNO3 :  GCARR(2.78E-04, 0.0E+00, 0.0);  {2017/07/14; Fisher2016; KRT,JAF,CCM,EAM,KHB,RHS}

Fix compatibility issue with ifort17

This update was included in v11-02f (approved 17 May 2018).

GEOS-Chem v11-02e with the netCDF diagnostics option enabled is not compatible with Intel Fortran compiler 17.0.4 and likely other ifort17 versions as well. The source code compiles but a string concatenation error is encountered in state_diag_mod.F90 during run-time. It appears that ifort17 is stricter than earlier versions of intel compilers with regards to concatenating indexed character arrays. Setting the indexed character array to a temporary variable prior to concatenation prevents the issue.

KPP errors with halogen chemistry and tropchem-based mechanisms

This update was included in v11-02f (approved 17 May 2018).

Melissa Sulprizio wrote:

Katie Travis discovered an issue starting with v11-02d when the halogen chemistry updates were introduced. When running 2x2.5 tropchem simulations for an extended period (usually a month will do), GEOS-Chem crashes with a KPP integrator error. This happens for both GEOS-FP and MERRA-2 met fields. We don’t seem to encounter these errors for 2x2.5 standard (i.e. UCX-based) simulations. I’m wondering if we need to change the tolerance values in v11-02? Right now, in flexchem_mod.F we have:

   !%%%%% CONVERGENCE CRITERIA %%%%%

   ! Absolute tolerance
   ATOL      = 1e-2_dp  

   ! Relative tolerance
   IF ( Input_Opt%LUCX  ) THEN
      ! UCX-based mechanisms
      !RTOL      = 2e-2_dp
      !RTOL      = 1e-2_dp
      RTOL      = 0.5e-2_dp
   ELSE
      ! Non-UCX mechanisms
      RTOL      = 2e-1_dp
   ENDIF

I ran two simulations to see if we can resolve the issue in the 2x2.5 tropchem simulations. In the first simulation I changed the convergence criteria (RTOL) to 1e-1_dp following Mat's suggestion and in the second I changed the value to 1e-2_dp. In both simulations, we still get the integrator errors (Forced exit from Rosenbrock due to the following error: Step size too small...) but the 1-month runs finish successfully because the error is not encountered twice for a given grid box in a given timestep. Also, comparing the two simulations, we see the integrator errors at different times and for different grid boxes.

Barron Henderson wrote:

I have a couple thoughts that you may have already tried. They basically boil down to finding the few species at fault and tightening tolerances for everything else.

First, add a print statement for SPC_NAMES and VAR and in flexchem_mod.F90 when the IERR is -7. That will help us to quickly see if any concentrations at cells are unexpected.

Second, add a print statement for Yerr after 535 in gckpp_Integrator.F90. That should further isolate the source of error and will only print when the error is triggered.

Hopefully, a few species will jump out. Then, the tolerances can targeted. Right now, it looks like tolerances are set as a vector, but all values are identical. The values are pretty loose for many species, but I suspect they were chosen to allow integration for a few radical species. One common approach for this situation is to identify a few key species and set the ATOL/RTOL separately for those species.

    # set default
    ATOL = 1e-3
    RTOL = 1e-5
    # set species specific
    ATOL(ind_O1D) = 1e-2
    RTOL(ind_O1D) = 1e-2
    ATOL(ind_XXX) = 1e-2
    RTOL(ind_XXX) = 1e-2

Tightening the tolerances will make it more stable, and oddly often faster.

Mat Evans wrote:

So even if we set the tolerance to be 1e-2_dp we still get a convergence error. Its hard to know what to advise here. It sounds like we need a bit of work to be done looking at this and looking at the situation that the convergence fails and to get an understanding of when we get the problem. However given the pressure at the moment to get v11.2 done I think my advise would be for us to move to using 1e-2 in the interim and we come back to this.

The major problem I can see from this is in the run time. I don’t know how much longer the simulation is to run with this as the convergence criteria.

Disable Xiao propane emissions to avoid double-counting with CEDS

This fix was incldued in GEOS-Chem v11-02-rc (issued 22 Jun 2018).

Lizzie Lundgren wrote:

I am turning off the XIAO inventory in v11-02 but just noticed Daniel said "for propane" while Christoph said to turn off the entire inventory. Christoph pointed out this would avoid double-counting C2H6 since we also get it from [the C2H6_2010 inventory of] Tzompa-Sosa et al. (2017)

Christoph Keller wrote:

I should have been more specific: in the current configuration, XIAO emissions are only used for propane. For ethane, the Tzompa-Sosa emissions always have priority over XIAO (hierarchy of 1000 vs. 5) and XIAO ethane emissions are thus ignored. The problem with propane is that CEDS and XIAO have the same hierarchy (=5) and the emissions are therefore added. Just disabling XIAO will fix this - and won't have an impact on ethane.

Bug fix: Specifying NO_REDUCED=no now compiles GEOS-Chem for reduced grids

This fix was included in v11-02a and approved on 12 May 2017.

Jiawei Zhang wrote:

I found a small but annoying bug in Makefile_header.mk. The problem is that if I use NO_REDUCED=n (i.e. use 47 levels) as a compile option, then the makefile will treat it as NO_REDUCED=yes (i.e. use 72 levels). The LLPAR parameter will then be set to 72 instead of 47, leading to unexpected behavior. That's because Makefile_header.mk contains something like:

      # %%%%% REDUCED VERTICAL GRID (default, unless specified otherwise) %%%%
      ifndef NO_REDUCED
        USER_DEFS        += -DGRIDREDUCED
      else
        REGEXP           :=(^[Yy]|^[Yy][Ee][Ss])
        ifeq ($(shell [[ "$(NO_REDUCED)" =~ $(REGEXP) ]] && echo true),true)
        endif
      endif

The GRIDREDUCED C-preprocessor switch will only be activated if NO_REDUCED is not provided. The following "yes" or "no" just doesn't matter because the nested ifeq statement doesn't do anything. With this problem, the only way to compile a 47L model is NOT providing the NO_REDUCED option. It also affects compiling GEOS-Chem from the geosfp_4x5_tropchem rundir, because NO_REDUCED=n is one of the default options.

We have now fixed this issue by setting the NO_REDUCED Makefile variable to "no" by default, and then evaluating its value in a separate IF statement. This code has now been added to the Makefile_header.mk.

  # %%%%% REDUCED VERTICAL GRID (default, unless specified otherwise) %%%%
  ifndef NO_REDUCED
    NO_REDUCED       :=no
  endif
  REGEXP              :=(^[Nn]|^[Nn][Oo])
  ifeq ($(shell [[ "$(NO_REDUCED)" =~ $(REGEXP) ]] && echo true),true)
    USER_DEFS        += -DGRIDREDUCED
  endif

This fix now will compile GEOS-Chem for 47 levels when NO_REDUCED=no is specified, or if NO_REDUCED is omitted.

Discrepancies in single-stage simulations vs multi-stage simulations

Jack Kodros wrote

I am having an issue re-starting simulations. I was trying to restart a simulation midway through the year using the restart file the sim had created, yet I noticed I started getting odd results.
To test things out I ran a tropchem sim starting in February and ran straight through until April. I then ran a second, separate, but identical sim with the March restart file and HEMCO restart file from the first sim. I then compared the two sim outputs for the month of March. I had expected to get identical results, but instead I get small differences. I am attaching a percent change plot of OC, BC, NH3, and SO4 from this simulation showing the changes.
This is a concerning issue for me because I will now get different results if my simulation runs straight through or if I have to restart the simulation part way through.

Christoph Keller wrote:

At least for standard GEOS-Chem the updates should be pretty simple. It should be as easy as adding a few more variables to the GEOS-Chem and HEMCO restart files:
Move PSC_RESTART variable from HEMCO restart file to GEOS-Chem restart file.

Archive fields DRY_TOTN, WET_TOTN, into HEMCO restart file.

Archive H2O2s, SO2s, and HSAVE_FOR_KPP as GEOS-Chem restart file variables. (NOTE: HSAVE_FOR_KPP might be obsolete in v11-02.)

 :GCST, in summary, can we use the GEIA natural NH3 emissions file at 1x1 resolution rather than 4x5? Currently the default is 4x5 and Eleanor from U York found large differences between these two files, where the 1x1 emissions are more consistent with observations. It looks like GEIA natural NH3 will eventually be retired and replaced with emissions that Amos Tai is working on, so this would be an interim fix.

The problem with propane is that CEDS and XIAO have the same hierarchy (=5) and the emissions are therefore added. Just disabling XIAO will fix this - and won't have an impact on ethane.</blockquote>
