This page includes information about GEOS-Chem 13.4.0 (currently under development)

Version overview

The following items have been added to GEOS-Chem 13.4.0 since the last GEOS-Chem version GEOS-Chem 13.3.1. Also see the following Github pages:

Feature Contributor(s) Model scope Notes and references
Updates that will affect full-chemistry benchmark simulations
Bug fix: Remove double-counting of HCl uptake on acidic sea salt Viral Shah (Harvard) Chemistry
Use updated definition of PM2.5; Add PM10 diagnostic Bob Yantosca (GCST) Diagnostics &
HEMCO bug fix: restore archiving via manual diagnostics (which had been inadvertently disabled in a prior update) Melissa Sulprizio (GCST)
Bob Yantosca (GCST)
Use degassing-only volcano emissions in GEOS-Chem benchmark simulations Christoph Keller (GMAO)
Daniel Jacob (Harvard)
Emissions &
  • geoschem/geos-chem #1005
  • This will make it easier to compare results to past benchmarks in case the benchmark year should change.
Updates that will NOT affect full-chemistry benchmark simulations
Updates to enable automated run directory creation Liam Bindle (GCST)
Melissa Sulprizio (GCST)
Run directory
Bug fix: Use REAL*8 precision in for CH3O2 + OH reaction definition in fullchem.eqn Bob Yantosca (GCST) Chemistry
Updated Rn-222 emissions for TransportTracers simulations Bo Zhang (NIA) Emissions
Updates that will only affect GCHP
Define a GCHP "Default" collection that will archive a small number of commonly-requested diagnostic fields Liam Bindle (GCST) Diagnostics

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.
