Feature Contributor(s) Model scope Notes and references
Updates that will affect full-chemistry benchmark simulations
Updating VOC fire emissions and adding lumped furan Colette Heald (MIT)
Tess Carter (MIT)
Reinstate Iy sink reactions on alkaline sea salt aerosol and remove IONO2 recycling on alkaline sea salt aerosol Becky Alexander (UW) Chemistry
Now use consistent behavior when the first call to the KPP integrator fails Bob Yantosca (Harvard) Chemistry
Prevent divide-by-zero error in sulfur chemistry Lizzie Lundgren (Harvard) Chemistry
Updates that will NOT affect full-chemistry benchmark simulations

Bob Yantosca (Harvard)
  • geoschem/geos-chem PR #1709
  • NOTE: Will not affect benchmarks, because the benchmark year is 2019, and we are only adding new years 2020-2022.
Reduce log file output in GEOS-Chem and HEMCO Bob Yantosca (Harvard) Structural
Remove `NcdfUtil/perl` directory from GEOS-Chem and HEMCO Bob Yantosca (Harvard) Structural
Do not halt benchmark simulations and integration/parallel tests if there are missing species in restart files and/or boundary conditions Bob Yantosca (Harvard) Testing
Updates that will only affect GCHP
