Full Changelog: 14.2.3...14.3.0

GEOS-Chem 14.2.3

Release date 01 Dec 2023

From CHANGELOG.md

Added

• GEOS-Chem Classic rundir script run/GCClassic/setupForRestarts.sh

Changed

• Added the -n aka --no-bootstrap option to integration tests to disable bootstrapping missing species in restart files
• Use integer parameters for species units instead of strings (for computational efficiency)
• Update error message for missing surface CH4 emissions with instructions on how to resolve the problem
• Change GCHP grid resolution threshold for lowering timesteps from C180 inclusive to C180 exclusive
• Read GEOS-Chem Classic restart file paths from the relevant download_data.yml file

Fixed

• Prevent POAEMISS from being assigned a value if not allocated (in carbon_mod.F90)
• Changed incorrect comment about static H2O option in GeosCore/input_mod.F90
• Fixed typos (GCClassic -> GCHP) written to GCHP integration test log files
