Description

GEOS-Chem 12.8.1
21 May 2020

This version fixes several issues that were identified during and after the benchmarking process for version 12.8.0:

  1. Update the dry-run download data script to make files group-writeable
  2. Add more timers for gas-phase chemistry
  3. Reduce the amount of memory that GEOS-Chem dry-runs require
  4. Add bounds-checking and floating point exceptions to CMake "Debug" target
  5. Fix incorrect indexing for AOD diagnostics
  6. Updates for GEOS-Chem "Classic" HISTORY diagnostics:
    • Fix for instantaneous timeseries diagnostics to avoid overwriting hour zero
    • Fix to allow diagnostics with frequency="End" to properly straddle year-end boundaries
  7. Allow for missing species in boundary conditions
  8. Disable FlexGrid checks to allow for running with any horizontal or vertical grid
  9. Fixes for WRF-GC and CESM-GC, including:
    • Fix Init_Pressure error for NZ /= 47, 72
    • Only perform pole-averaging of regridded data if actually regridding to the poles
    • Add a State_Grid%ID field
  10. Add fix for POPs emissions diagnostics
  11. Avoid memory corruption bug in HEMCO when certain debug flags are on
  12. Fix bug causing seg fault when ConcAboveSfc diagnostic collection is on
  13. Fix bug causing crash if not starting on the first day and time of the month
  14. Fix incorrect GCHP config file entry for surf_iodide source file in 12.8.0
  15. Avoid unexpected behavior if dynamic timestep is changed to non-default values
  16. Fix input data to avoid crashing in late Dec/early Jan if using offline biogenic VOCs
  17. Add internal state met variables to benchmark and transport tracers simulations
  18. Enable all budget diagnostics output in GCHP transport tracer simulation by default
