Overview
Under development. Expected release date 02/01/2012
- Previous version: GEOS-Chem_Adjoint_v31
- Next version: GEOS-Chem_Adjoint_v33
What's new in this version
Updates to forward model
Update tagged CO simulation (adj32_017)
Several updates from Zhe Jiang have been implemented for the tagged-CO implementation. See also changes to the adjoint model, GEOS-Chem_Adjoint_v32#Update_tagged_CO_simulation_.28adj32_017.29
Update to tagged_co_mod.f
tagged_co_mod.f has been updated to distribute emissions through the boundary layer and removing obsolete COSF, TIME_STEPS, GET_CO_CH4, SET_CO_CH4, and GET_OPT_CO.
Updates to time_mod.f for tagged-CO
Zhe Jiang wrote
- I currently found it perhaps can only affect tagged-CO inversion. Thus, it can not be said as a BUG.
- For example, if we do our inversion for June 1-15, when the backward running, because June 15 is not the last day of the calendar month, these emissions will not be read. However, we don't need to read them since the model will use the value in the forward run. For the tagged-CO backward run, the CH4 concentration will only be read if June 15 is the last day of the calendar year. Thus, in the original code, the CH4 concentration, and thus gradient on CH4 oxidation, is ZERO.
IF ( ITS_A_NEW_YEAR() ) THEN
CALL GET_GLOBAL_CH4( GET_YEAR(), .TRUE., A3090S, A0030S, A0030N, A3090N )
ENDIF
- In my previous code, I saved the CH4 concentration in the forward run and then read them in the backward run. After I modified time_mod.f, I have removed the code for the CH4 saving/reading. Anyway, the effect is trivial. I can solve the problem in the tagged_CO inversion by modifying the previous code.
To address these issues, subroutines ITS_A_NEW_MONTH and ITS_A_NEW_YEAR have been updated in time_mod.f.

Update several files to v9 code to support full-chem nested simulation (adj32_015)
Updates to the following files were made by Zhe Jiang to support the NESTED_NA and NESTED_SD simulation:
Update DEAD dust emissions for nested simulations and MERRA (v9-01-01)
When the forward model was updated to support MERRA, the dust emissions got retuned MERRA_implementation_details#Dust_emissions. But also the emissions for GEOS-5 were affected, and support was added for nested grid.
The dust_dead_mod.f file has been updated to match that in v9-01-01 (dust_dead_mod.f,v 1.3 2010/02/02 16:57:53 bmy). Common blocks CMN_SIZE and CMN_GCTM are reinstated for backwards compatibility.
Updated TOMS O3
toms_mod.f was updated to v9-01-02. This uses the newer TOMS inventory TOMS_200906 and allows for rescaling of years up to 2008 (previous version stopped at 2007).
cac_mod.f
cac_mod.f was updated to v9-01-02.
emissions_mod.f
emissions_mod.f was updated to support GRID05x0666 for CAC, NEI05 and EMEP emissions following v9-01-02.
file_mod.f
file_mod.f was updated to include IU_BC_05x06.
CMN_SIZE
CMN_SIZE was updated to include size of NA and SD nested domain.
commsoil.h
commsoil.h was updated to include size of NA and SD nested domain.
define.h
define.h was updated to include the NESTED_SD option.
tpcore_bc_mod.f
tpcore_bc_mod.f has been updated to include
- OPEN_BC_FILE_05x0666
- SAVE_GLOBAL_TPCORE_BC_05x0666
- DO_WINDOW_TPCORE_BC_05x0666
- CLEAN_WINDOW_TPCORE_BC_05x0666
- READ_WINDOW_TPCORE_BC_05x0666
- ITS_TIME_FOR_BC_05x0666INIT_TPCORE_BC_05x0666
and the BC_05x06 array.
regrid_1x1_mod.f
regrid_1x1_mod has been updated to support the NESTED_SD domain.
Update lightning_nox_mod.f
acetone_mod.f
acetone_mod.f has been updated to support the nested domains. It now matches v9-01-02, with the additional update for the adjoint that we do not multiply and divide by ACETONE, thus making OCEAN_SINK_ACET self-adjoint.
input_mod.f
input_mod.f has been updated in several places to support nested domains.
transport_mod.f
transport_mod.f has been updated to support the NESTED_SD domain.
co2_mod.f
co2_mod.f has been updated to support nested domains.

nei05 and input_mod.f
nei2005_anthro_mod.f and input_mod.f have been updates, see GEOS-Chem_Adjoint_v32#Fixes_for_minor_issues_affecting_nested-grid_simulations_.28v9_01_02e.29
Bug fixes in forward model
Ionic strength below zero in rpmares (adj32_001)
On prospero, we often get the message: Ionic strength below zero...negative concentrations.
Despite the setting of negative roots to zero, sometimes the code still ends up with negative CRUTES. Trap for it here to prevent mysterious crashing later. Also, add the following
!IF ( CRUTES(1) .ne. ABS(CRUTES(1) ) ) CRUTES(1)=1d9
!IF ( CRUTES(2) .ne. ABS(CRUTES(2) ) ) CRUTES(2)=1d9
!IF ( CRUTES(3) .ne. ABS(CRUTES(3) ) ) CRUTES(3)=1d9
which for some reason (I have no idea why) prevents the code from returning a negative CRUTES on prospero.

Updated to REGRID_05x0666_NESTED for non-standard domains (v?-?-?)
Zhe Jiang wrote
- I revised the SUBROUTINE REGRID_05x0666_NESTED.
- The problem in the original code is that the Longitude of LL (Left-Low of nested window) has to be even number and the latitude of LL has to be integer number. It has no influence on our standard NA/CH/EU nested setting.
- I think it would be safer to fix this problem because we perhaps need to define new nested window in future.
This subroutine has now been replaced with Zhe's update. Not sure if there is a corresponding update in the v9 forward model yet.

Fix variable declarations in UPBDFLX_NOY (adj32_008)
Thomas Walker noted that having DTDYN, AIRDENS, PNOY declared as REAL*4 can lead to overflow in the adjoint model. The upbdflx_mod.f has now been updated to use REAL*8 instead.

Updates to adjoint model
Updates to aerosol direct radiative forcing adjoint
Several updates in lidort_mod.f and mie_mod.f:
- From Farhan Akhtar, now include primary OC in the LIDORT radiative forcing calculation.
- Now switch back to using analytic derivatives from mie table rather than FD

Dust adjoint and MODIS AOD observation operator (adj32_011)
From Richard Xiaoguang Xu at UNL, the dust adjoint includes sensitivity with respect to dust emissions from the DEAD module. Also included in this update is an observation operator for assimilating AOD observations from MODIS using the UNL retrieval.
--Daven 00:23, 13 January 2012 (EST)
Inverse Hessian approximation (adj32_012)
The inverse Hessian approximation (e.g., Henze et al., 2009) using the DFP formula is now implemented with the LINVH flag in input.gcadj. Instructions for how to perform this calculation are included in the UPDATE_HESSIAN subroutine in the new inv_hessian_mod.f file.
--Daven 00:23, 13 January 2012 (EST)
Offline aerosol adjoint. (adj32_013)
Yuhao Mao and Qinbin Li at UCLA have implemented the offline aerosol simulation adjoint for black carbon. This update also included an observation operator for measurements of these species at IMPROVE sites, IMPROVE_BC_OC_OBS and improve_bc_mod.f.
The offline aerosol adjoint will also work for the recently implemented dust aerosol adjoint (it does not yet include support for sulfate aerosol, sea salt or SOA). For example, you may now run with input.geos

Augmented list of supported VOC sensitivities (adj32_014)
From Kateryna Lapina, sensitivities of anthropogenic, biofuel and biomass burning emissions of all VOCs (ALK4, MEK, ALD2, PRPE, C3H8, CH2O C2H6). To implement, simply list these in input.gcadj as:

Several updates to support nested full chemistry adjoint (adj32_015)
Several updates from Zhe Jiang support running the adjoint full-chemistry simulation over the NESTED_NA and NESTED_SD domain. The latter is a new domain, like NESTED_NA, but slightly less padding around NA.
Support nested in emissions_adj.f
emissions_adj.f has been updated to support nested emissions from the CAC, NEI05 and EMEP inventories.
Cleanup code in adj_arrays_mod.f
Remove obsolete variable NOR in adj_arrays_mod.f
--Daven 15:01, 18 January 2012 (EST)
Do not call GET_BOUNDING_BOX in input_adj_mod.f
When calculating IFD and JFD from a user specified latitude and longitude, the call to GET_BOUNDING_BOX causes a crash, so we need to modify this part of the code to work on the nested domain. For now, just re-order the code so that this is only called if USEINDEX is false, and run the nested code with USEINDEX true.
MOPITT v5 observation operator (adj32_016)
Zhe Jiang added support for the MOPITT v5 products.
- Add MOPITT_V5_CO_OBS pre-processor flag to define_adj.h
- Updates to adj_arrays_mod.f, mopitt_obs_mod.f , HdfVdModule.f90, input_adj_mod.f.
--Daven 15:01, 18 January 2012 (EST)
Updates for tagged CO simulation (adj32_017)
Several updates from Zhe Jiang have been implemented for the tagged-CO implementation. See also changes to the forward model, GEOS-Chem_Adjoint_v32#Updates_for_tagged_CO_simulation__.28adj32_017.29
Include CH4 gradient
Update inverse_mod.f so that oxidation of CH4 is incorporated in the gradient
Cleanup and small fixes to tagged_co_adj_mod.f
Remove COSF and TIME_STEPS in tagged_co_adj_mod.f.
Cleanup and merge CALC_APRIORI
Updates for calculation of the penalty term:
- Now valid for full chemistry and tagged CO simulations
- Add subroutine READ_APERROR
Enforce factor of 0.5 in cost function definition
A consequence of the merging of the full-chem and CO routines in CALC_APRIORI is that the definition of the cost function needs to be made consistent. Originally, the CO code omitted the factors of 1/2 in both terms of the cost function. To correct for this, the cost function (and adjoint forcing) has been updated in the following CO observation operators to match the definition in the full-chem simulation:
- airs_co_obs_mod.f
- mopitt_obs_mod.f
- sciabr_co_obs_mod

Bug fixes in adjoint model
Mover error checking for O3 assimilation (adj32_002)
Nicolas Bousserez wrote:
- the code crashes in "input_adj_mod.f" when doing the checking of observation settings (see line 2027 in my code). It is apparently due to "IDCSPEC_ADJ", which is not allocated/defined yet at the time the program executes those lines. I'm skipping these checks for now then. Note: The code crashes also when using "TES_O3_OBS" instead of "SCIA_DAL_NO2_OBS", so it is not related to what I implemented apparently.
The following block of code has been moved from input_adj_mod.f to subroutine INIT_CSPEC_ADJ in adj_arrays_mod.f, as it can only be called after the CSPEC variables have been initialized.
#elif defined ( TES_O3_OBS )

- because it seems like I'm already updating the adjoint of NO2 in "sciadal_no2_obs_mod.f" through CSPEC_AFTER_CHEM_ADJ. I would like to be sure that it is correct though.
Daven Henze wrote:
- Yes, that is correct. I didn't want to take it out incase you had built your obs operator using CSPEC_NO2_ADJ. But since you used the more generic CSPEC_AFTER_CHEM_ADJ, then we can delete this section entirely and use the section higher up in this file ( IF (LCSPEC_OBS) ...) to apply the forcing from your obs operator to CSPEC_ADJ.
Now use CSPEC_AFTER_CHEM_ADJ instead of CSPEC_NO2_ADJ in chemdr_adj.f.

Fix to NaNs in STT_ADJ everywhere after adjoint of partitioning (adj32_004)
The forward gas-phase chemical solver may sometimes need to repeat the internal integration of the reaction rate ODEs within a single grid cell. When this happens, we now only redo the model calculation during the forward model run, not the adjoint, as this can lead to a corrupt CSPEC_ADJ array globally (not sure how that happens, but it does), eventually triggering a check for NaNs after the partitioning adjoint. See updates to chemistry_mod.f and gckpp_adj_Integrator.f90. Thanks to Richard Xu for helping pinpoint this bug.

Fix to NaNs in sulfate aerosol adjoint tracers (adj32_005)
Owing to cancelation of errors, it's possible to seemingly randomly end up with NaNs coming out of CHEM_SO2_ADJ . This can happen if L3 ends up equaling 1d0 exactly. We now trap for this and skip in the rate event this happens.

Fix for reseting deposition adjoints (adj32_006)
Fabien Paulot wrote:
- It seems it's "a bug" in the code. To keep track of the dry deposition flux of HNO3 I use dryhno3 (in cspec array). The CSPEC_ADJ(DRYHNO3,:) should be reset to zero at every time step but it is not. That's because you are saving in chk_cspec before it is reset to zero. Easy fix, just force to zero in chemdr_adj before the forcing is applied et voila, it works (the adjoint does not diverge any more after one hour). It should not affect anything as long as there is no forcing on dryhno3 (or any dry dep counters for that matter).
We add the following to reset the dry dep adjoints in chemdr_adj.f:

- From a dimensional analysis this would seem plausible. It would also explain some of the errors I'm currently fighting with. If this is correct, then a short comment should perhaps be added to the code.
