Benchmark assessment form

NOTE: This plot is still being filled out.

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
 Lizzie Lundgren (GCST)
Embed GEOS code within select GCHP files Lizzie Lundgren (GCST)
