+ | === v11-02f-Run0 === | ||
+ | |||
+ | 1-year benchmark simulation v11-02f-Run0 contained all of the same updates described in [[#v11-02f-Run1|v11-02f-Run1]] above, PLUS | ||
+ | |||
+ | *[[GEOS-Chem_v11-02#Use_1x1_GEIA_NH3_emissions|Use 1° x 1° GEIA natural NH3 emissions data]] | ||
+ | |||
+ | Subsequent analysis revealed that the switch from the 4° x 5° GEIA NH3 emissions data to the 1° x 1° data produced 20X too much NH3 emissions as expected. We believe that this is likely attributed to an regridding error during the preparation of the original file. | ||
+ | |||
+ | We have since reverted to using the 1° x 1° GEIA natural NH3 emissions data, which is benchmarked with [[#v11-02f-Run1|v11-02f-Run1]]. We have also de-listed the v11-02f-Run0 benchmark from the wiki, given that it contained clearly incorrect emissions. | ||

+ | *N2O, OCS, CH4 | ||
+ | *IONITA | ||
+ | |||
+ | |-valign="top" | ||
+ | |Comments on SURFACE differences: | ||
+ | | | ||
+ | *Most of these differences can be attributed to the new emissions inventories that were added (C2H6, DICE-Africa, Trash burning, etc.) | ||
+ | *Large differences in NH3 can be attributed to using the GEIA natural NH3 emissions file at 1° x 1° resolution, plus some new emission inventories (such as Arctic Seabirds). | ||
+ | *N2O5 uptake was modified in this version leading to an increase in concentration over South America but a decrease in mostly N mid-latitudes. | ||
+ | *Some of the changes in the NOy species could be attributed to the fix that was made in UCX for mesospheric NOy. | ||
+ | *Differences in HCl can be attributed to the fix of an incorrect Henry's law parameter. | ||
+ | *Species for which there are biogenic emissions are affected by the switch to the 0.25° x 0.25° MODIS LAI data. This might also affect dry deposition. | ||
+ | *NOTE: Some large ratios (e.g. of isoprene or SOA species over oceans) might be due to small-number statistics, where concentrations are already very low. | ||
+ | |||
+ | |-valign="top" | ||
+ | |At 500 hPa, list all species that changed by 10% or more: | ||
+ | |Mostly the same species as listed in SURFACE DIFFERENCES | ||
+ | |||
+ | |-valign="top" | ||
+ | |Comments on 500 hPa differences: | ||

+ | *See comments for surface differences | ||
+ | *CO is more or less unchanged at 500hPa | ||

+ | |-valign="top" | ||
+ | |Comments on EMISSION RATIO differences: | ||
+ | | | ||
+ | *Differences are largely caused by the introduction of new inventories as listed in the table above. | ||

Latest revision as of 18:49, 28 May 2020
GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12.0.0. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. For a complete description of the new versioning system, please see our GEOS-Chem version numbering system wiki page.
On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem v11-02.
Contents
- 1 1-year full-chemistry benchmarks
- 2 1-month benchmarks
- 3 1-year Rn-Pb-Be benchmarks
- 4 High Performance Option benchmarks
1-year full-chemistry benchmarks
v11-02-final (aka 12.0.0)
Please see visit this page for details on 1-year benchmark simulation 12.0.0-Run0.
v11-02f-Run1
This 1-year benchmark simulation was approved by the GEOS-Chem Steering Committee on 11 Jun 2018.
Three GEOS-Chem model versions were compared to each other:

v11-02f-Run0
1-year benchmark simulation v11-02f-Run0 contained all of the same updates described in v11-02f-Run1 above, PLUS
Subsequent analysis revealed that the switch from the 4° x 5° GEIA NH3 emissions data to the 1° x 1° data produced 20X too much NH3 emissions as expected. We believe that this is likely attributed to an regridding error during the preparation of the original file.
We have since reverted to using the 1° x 1° GEIA natural NH3 emissions data, which is benchmarked with v11-02f-Run1. We have also de-listed the v11-02f-Run0 benchmark from the wiki, given that it contained clearly incorrect emissions.

New plots were added this version for evaluating the two SOA schemes, including:
- Species concentration maps at surface and 500 hPa
- Zonal mean species concentration plots
- Two sets of PM2.5 plots (PM2.5 with complex SOA species; PM2.5 with simple SOA species)

Comments about the 1-year benchmark v11-02c-Run0
Computing PM2.5 and AOD
Jeff Pierce wrote:
- Can you tell us which SOA is being included into the PM2.5 and AOD calculations for the three different simulations? I assume the SOA scheme changes between these different simulations?
Melissa Sulprizio responded:
- Following the recommendation of the Aerosol WG leaders, simple SOA is the default in all full-chemistry simulations for v11-02c and later. However, for the benchmark simulations we turn on both complex SOA and simple SOA so that we can continually evaluate the two schemes. That means, when a user downloads v11-02 and creates a run directory for the full-chemistry simulations (tropchem, standard w/ UCX, etc.), input.geos will automatically be set up to use simple SOA. The complex SOA option will only be turned on if a user creates a run directory for the “complexSOA”, “complexSOA_SVPOA”, or “benchmark” simulation. As I mentioned below, by default in aerosol_mod.F, when complex SOA is turned on the complex SOA species will be used in the calculation of PM2.5 and AOD over the simple SOA species to avoid double counting. This is only an issue in the benchmark simulations when both options are turned on – in all other simulations, it will be clear whether complex SOA or simple SOA species are used in the calculations based on the settings in input.geos.
Ocean ALD2
Dylan Millet wrote:
- I missed it in the prior benchmark but it seems as part of the PAN update the ocean acetaldehyde source went into the model. That seems fine to me but it is a quite large global reactivity source (can someone tell me if the 66TgC for ALD2osr in the emission summary file is gross or net? I hope gross) so there needs to be traceability for that in the model narrative (e.g. if it's based on Millet et al. 2010 or on something else).
Melissa Sulprizio responded:
- The ALD2 ocean source (ALD2osr) in the emissions summary file is gross. HEMCO handles the ALD2 ocean sink and we can’t currently output that as a diagnostic. This is similar to how we currently handle the ACET ocean source/sink. Here are comments from Christoph added during the implementation from HEMCO:
! (1 ) in HEMCO, Acetone sink from OCEAN is handled by drydep and the ! corresponding diagnostics. If needed, we can write a wrapper that ! explicitly calculates the Acetone ocean sink. (ckeller, 08/04/14)
Halogens
Dylan Millet wrote:
- There are some large relative changes for many of the halogen species, which I guess is linked to OH/NOx feedbacks from the isoprene chemistry. It would be great if someone close to the halogen stuff can confirm that they're comfortable with the changes.
Mat Evans wrote:
- So as Dylan says the halogens change significantly with these updated. I think most of these changes relate to the increases in the oceanic ALD2 source. ALD2 reacts pretty quickly with Br resulting in HBr. So BrOx concentrations tend to decrease and HBr increases.
- This is useful as we currently don’t include the sea-salt debromination source. It seems likely that the additional oceanic oVOCs leads to a shorter BrOx lifetime and so might allow for an increase in the Br source consistent with the observational BrO constraint we’ll have to see in future releases.

Comparison with high performance option enabled: (new in this version) |
We now include a plots subdirectory called gchp_comparison containing 1-month standard simulation output comparisons using the standard "classic" capabilities (GCC) and the high performance option (GCHP). GCHP features the same science as GCC but operates on a cubed-sphere grid and is parallelized using a message-passing interface (MPI) implementation. GCHP improves upon GCC by (1) enabling more accurate transport, and (2) providing efficient scaling making finer resolution global simulations possible. There is a separate benchmark approval form for the comparison of GCHP and GCC. See the Assessment form for the 1-month benchmark of v11-02b with high performance option. | ||||||||||||||

Additional or summary comments: | Removal of biomass burning updates
After the 1-month benchmark for v11-02a, the GCSC decided we should remove the code updates for vertically distributed biomass burning emissions (see this wiki post for more details). In addition, after the 1-year benchmark v11-02a-Run0, the GCSC asked that we comment out the partitioning of NOx biomass burning emissions directly to PAN and HNO3 (see this wiki post for more details). An unofficial 1-month benchmark was run for v11-02a to evaluate the model changes with these two biomass burning updates removed. The plots for that run may be viewed at: Results from our v11-02a benchmark using the GNU Fortran Compiler In order to evaluate the performance of GEOS-Chem using the the free and open source GNU Fortran compiler, we performed an additional 1-month benchmark for v11-02a. For this additional benchamark, we used GNU Fortran v6.2.0 to compile GEOS-Chem instead of our usual Intel Fortran Compiler version 11.1.069. For more details, see this post on our GNU Fortran compiler wiki page. Summary: The benchmark using GNU Fortran yielded essentially identical results to the benchmark using Intel Fortran. This is very encouraging, as it will allow GEOS-Chem development to take place on computational platforms that do not have proprietary compilers (such as Intel Fortran or PGI Fortran), which can be prohibitively expensive to purchase. | ||||||||||||||||||||||||||||||||||||||||||||

1-year Rn-Pb-Be benchmarks
v11-02e-RnPbBePasv-Run2
Two 1-year Rn-Pb-Be simulations were performed using GEOS-Chem v11-02e. The simulations utilized 4° x 5° GEOS-FP met fields for the year 2016, with a 4-year spinup.
For comparison of the Pb-210 and Be-7 budgets to previous versions, please see the following posts on the Rn-Pb-Be simulation wiki page:
Please note that we include a passive species to test for mass conservation in GEOS-Chem transport. The passive tracer continues to show that mass is not conserved when the non-local PBL mixing scheme (VDIFF) is turned on. We first discovered this issue in v11-01 and continue to complete the 1-year Rn-Pb-Be simulations with and without non-local PBL mixing to track this issue.

High Performance Option benchmarks
v11-02b HP 1-month
This section includes the assessment form for the 1-month benchmark simulation GEOS-Chem v11-02b with high performance v11-02b. GCHP features the same science as GCC but operates on a cubed-sphere grid and is parallelized using a message-passing interface (MPI) implementation. GCHP improves upon GCC by (1) enabling more accurate transport, and (2) providing efficient scaling making finer resolution global simulations possible.
See also the assessment form for the 1-month v11-02b benchmark simulation using the standard "classic" capability.
Description | |
---|---|
New features added: |
As this is the first formal GCHP benchmark, new features include the high performance model capability in its entirety. This includes all recent feature updates included in GCHP v11-02b as well as updates in v1.0.0 that were introduced over many years and are too numerous to list. |
GEOS-Chem version: | GCHP v11-02b |
Meteorology fields: | GEOS-FP (72L), 2x2.5, July 2013 NOTE: Input 2x2.5 met-fields are regridded to cubed-sphere grid resolution c24 (approximately equivalent to 4x5) within GCHP. In contrast, the GCC simulations in this comparison use input 4x5 met-fields. |
Cubed-sphere resolution: | c24 |
1-month benchmark finished on: | Thurs June 12 22:01:08 EDT 2017 |
Performance statistics: |
|
Compared to benchmark: | GEOS-Chem Classic v11-02b |
Additional comments: |
We compared GEOS-Chem with and without the high performance option (GCHP and GCC respectively) for two different scenarios:
The out-of-the-box comparison uses as-is code and run directory settings for both GCHP and GCC. Each simulation uses restart files regridded from higher resolution 2x2.5. GCHP uses input 2x2.5 met-fields which are regridded to cubed-sphere grid resolution c24 (approximately equivalent to 4x5) within the model. In contrast, the GCC simulations in this comparison use input 4x5 met-fields. GCC is compiled with netcdf diagnostics turned on and binary diagnostics turned off. GCHP output data are regridded from c24 (cubed-sphere grid) to 1x1.25 and GCC output data are regridded from 4x5 to 1x1.25 for comparison plotting. The custom comparison includes additional modifications to the GCC code base and run directory to remove certain remaining known differences between GCHP and GCC. These include the following changes to GCC:
NOTE: Non-concentration diagnostics are not yet implemented in GCHP. The v11-02b HP benchmark therefore includes only comparisons of species concentrations. A complete set of diagnostics will be available pending implementation of netCDF diagnostics in GEOS-Chem (in progress). |

Methyl chloroform lifetime: | Diagnostic not yet implemented. See note in additional comments section above. |
Did either of these change by more than 5%? | N/A |
At the SURFACE, list all species that changed by 10% or more: |
|
Comments on SURFACE differences: |
Sources of general differences include the following:
|
At 500 hPa, list all species that changed by 10% or more: | All species changed by 10% or more except O3, CO, ACET, and all species listed above for the surface. |
Comments on 500 hPa differences: | See comments on surface differences above. |
In the ZONAL MEAN differences, list all species that changed by 10% or more: | All species changed by 10% or more. |
Comments on ZONAL MEAN differences: |
|
Additional or summary comments: |
Overall, the largest fractional differences between GCC and GCHP occur where concentrations are very low. Differences between GCHP and GCC are primarily due to the effects of the following:
The concentration differences we see are inevitable given the fundamental differences between GEOS-Chem with and without high performance capability. |
