  2. Fix molecular weight of ethanol (EOH) in species_database.yml
  3. Fix typo in CloudHet function in gckpp_HetRates.F90

Bob Yantosca (GCST)
Specialty simulation
  • See geoschem/geos-chem #769
  • Daily data files are very large; we have compressed some.
  • Added trace metal species as a standalone simulation, so as not to burden other simulations with large data I/O
Features only affecting GCHP:
Set lev positive 'up' for all diagnostic files except Emissions Lizzie Lundgren (GCST) Output
Update MAPL to prevent minimum CMake version 3.14 Liam Bindle (WUStL) MAPL
Updates to GCHP sample run scripts including multi-run bug fix Lizzie Lundgren (GCST) Run directory

New data directories

The following data directories have been added or updated in this version. You will have to download the directories relevant to your simulation.

Benchmark Plots and Tables

NOTES:

  • Enable PDF bookmarks in the file links to navigate between species. See the Species in GEOS-Chem wiki page for species definitions and details. If you do not see bookmarks in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.
  • Species categories and lumped species are defined in YAML files within the GEOS-Chem post-processing software GCPy.

Overview
Below we summarize the notable changes caused by specific updates. Supplementary plots may be viewed at http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/InternalBenchmarks/.

1. CEDS v2 emissions through 2019

This update changes the default global anthropogenic emissions inventory from the CEDS GBD-MAPS emissions (McDuffie et al., 2020) to CEDS v_2021_04_21. A comparison of 1-year HEMCO standalone simulations with two CEDS inventories (all other emissions off) may be found at http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/CEDS_comparison/. The impact on total emissions from CEDS in the 1-month benchmark is:

3. Improved wet scavenging from Luo et al. (2020) (as option)

Some small differences at the level of numerical noise (i.e. differences ~1e-6X or ~1e-7X smaller than values) still occur even when the default wetdep scheme is used. This is because we now better enforce REAL*8 precision by adding _fp or _f8 suffixes to numerical constants where they were lacking in both Luo and default wetdep schemes.
Additional 1-month benchmarks with the Luo et al. (2020) wet deposition scheme were also completed. Results of those benchmarks are linked above.

4. Blowing snow emissions of sea salt and sea salt bromide

Lyatt Jaegle wrote, "I have looked at the benchmaks and it looks good to me, with changes in SALA, SALC, BrSALA and BrSALC as expected. As this is a simulation for July, the largest changes are seen in the SH polar regions. With decreasing sea salt emissions from the oceans due to to cold temperature suppression and increased emissions over sea ice due to blowing snow sea salt emissions." The impact on emissions from the SeaSalt extension is:

5. Add carbon to species scale factors to AEIC VOC emissions

This update fixes an issue introduced in GEOS-Chem 13.0.0 when carbon-based units were removed from HEMCO and GEOS-Chem. AEIC emissions were never updated to include the proper carbon to species scale factors. This fix increases VOC species concentrations aloft. The impact on emissions from that inventory is:

NOTES:

  • Enable PDF bookmarks in the file links to navigate between species. See the Species in GEOS-Chem wiki page for species definitions and details. If you do not see bookmarks in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.
  • Species categories and lumped species are defined in YAML files within the GEOS-Chem post-processing software GCPy.
