NOTES:

  1. Category and lumped species definitions are simple to adjust. Updating them requires only editing the json files.
  2. All plots created with GCPy have PDF bookmarks. If you do not see them in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.

Description
New features added into GEOS-Chem
Feature Submitted by
Features affecting the full-chemistry simulation:
Fix inconsistency for species H2402 between GCHP and GEOS-Chem "Classic" Sebastian Eastham (MIT)
GCST
Bug fixes for the FAST-JX photolysis mechanism: Bob Yantosca (GCST)
Updates and fixes for HEMCO diagnostics, including:
  • Enable saving out fertilizer NOx emissions
  • Lightning NOx emissions are 3D not, 2D
  • HNO3 ship emissions are 2D, not 3D
  • Update and fill in missing inventory diagnostics (currently used in only in benchmark simulations)
 Melissa Sulprizio (GCST)
Features NOT affecting the full-chemistry simulation:
Extending the CEDS anthropogenic emissions inventory to include 1750-1949 and additional VOC species Melissa Sulprizio (GCST)
Features only affecting GCHP:
Disable Br2 offline seasalt emissions to match GEOS-Chem Classic default Sebastian Eastham (MIT)
Assorted GCHP run directory feature updates
  • Rename Makefile clean and build options
  • Remove deprecated Makefile/build.sh clean and build options
  • Remove aliases from sample run scripts
  • Remove output file runConfig.log; send to gchp.log instead
  • Update benchmark run directory to match GEOS-Chem Classic settings

Global mean OH from log file (% change): 12.5657321664519 x 105 molec/cm3 (0.27%)

Methane lifetime (% change): 8.3059 years (-0.39%)
At the SURFACE, list all species that changed by 10% or more:
  • Primary: O3 OH NOx
  • Aerosols: NH4 NIT SO4 AERI BrSALA BrSALC ISALA ISALC NITS SO4s SOA_Complex SOA_Simple
  • Bromine: All Br species EXCEPT ChBr CH2Br2 CHBr3
  • Chlorine: Cly ClOx Cl ClO Cl2 Cl2O2 ClOO ClNO2 ClNO3 HOCl HCl

  • Nitrogen: NOx NOy HNO2 HNO3 HNO4 IPMN NIT NO NO2 NO3 N2O5 MPN PAN PPN NHx NH4

  • Secondary Organics: MEK MVK CH2O HPALD MP ISOPN IEPOX ACTA
  • ROy: H2O2 H HO2 O1D OH RO2

Sulfur: SOx SO2 SO4

Comments on SURFACE differences:
  • As emissions did not change between versions, we can likely attribute these to the updates to FAST-JX.
  • Many species showed larger percent differences in areas where concentrations were very small.
At 500hPA, list all species that changed by 10% or more: Same as for surface
Comments on 500 hPa differences:
  • See comments for surface differences
In ZONAL MEANS, list all species that changed by 10% or more: Same as for surface
Comments on ZONAL MEAN differences:
  • See comments for surface differences
In the EMISSION RATIO maps, list all species that changed by 10% or more: None
Comments on EMISSION RATIO differences: Emissions in 12.3.2 are 100% identical to 12.3.0
Additional or summary comments: The bug fixes for FAST-JX resulted in very small changes w/r/t the 12.3.0 1-month benchmark:
  • Mean OH changed by +0.2782%
  • MCF lifetime changed by -0.3597%
  • CH4 lifetime changed by -0.3936%

The fix to make species H2402 consistent between GCHP and GC "Classic" resulted in very minor additional changes on top of the FAST-JX fixes:

  • Mean OH changed by -0.0002%
  • MCF lifetime was unchanged
  • CH4 lifetime changed by +0.0012%

So it appears that most of the changes between 12.3.0 and 12.3.2 are being driven by the bug fixes to FAST-JX.

Comments on additional differences in GCHP: To be filled out by GCHP WG
