GEOS-Chem Classic 13.3.1
Release date: 15 Nov 2021
Contains fixes for minor issues that were discovered during the 13.3.0 benchmarking process:
- Diagnostic fixes:
- Fix incorrect units in ProdLoss diagnostic output
- Bug fix: Remove second underscore from State_Chm Hg simulation fields
- Remove duplicate unit conversion from kg/kg dry to v/v dry in planeflight_mod.F90
- Now allow GEOS-Chem Classic History collection names to contain an underscore
- Other updates and fixes:
- Stop gracefully if the chemical solver fails to converge to a solution twice in a row
- Also print out concentrations and reaction rates at the affected grid box, which can aid in debugging the problem
- Fix call to timers in fullchem_mod.F90
- Use default timesteps (transport=600s, chemistry=1200s) for nested-grid simulations using 0.5° x 0.625° grids
- EXCEPTION: CH4 simulations at 0.5° x 0.625° will still use transport=300s, chemistry=600s timesteps
- Fix incorrect file path in TOMAS routine YuIMN_Code.F90
- GCHP updates and fixes:
- Fix incorrect file timestamp with freq=1hr and duration=24hr
- The cleanRunDir.sh script now removes additional log files produced by GCHP
