Updates that will affect full-chemistry benchmark simulations

  • Migrate sulfate chemistry into KPP
  • Convert the HOCl & HOBr reactions with dissolved SO2 to use gas phase SO2
  • Turn off sea salt debromination by default
  • Fix bug in Henry law CALC_HEFF routine in hetchem computations
  • Bug fix: Remove double-counting of HCl uptake on acidic sea salt
  • Update surface resistance for ozone deposition to ice/snow
  • Update to HEMCO version 3.4.0
  • AEIC 2019 aircraft emissions inventory
  • Use degassing-only volcano emissions in GEOS-Chem benchmark simulations
  • Fix end year for CEDS_NO_SHIP and MULTISEAICE entries in HEMCO_Config.rc
  • Fix parallelization errors in GEOS-Chem Classic and add updates for better numerical stability
  • Use updated definition of PM2.5; Add PM10 diagnostic

Updates that will NOT affect full-chemistry benchmark simulations

  • Updated Hg chemistry in KPP
    • NOTE: Still undergoing validation, a fix may be issued in a patch version (e.g. 13.4.1)
  • Bug fix: Use REAL*8 precision in for CH3O2 + OH reaction definition in fullchem.eqn
  • Updated Global Inventory of Methane Emissions from Oil/Gas/Coal (GFEI v2)
  • Anthropogenic Methane Emission Inventory for Canada
  • Use EDGARv6 global anthro emissions for CH4 simulation
  • Updated Rn-222 emissions for TransportTracers simulations
  • Retire HEMCO extension for CH4 wetland emissions
  • Updates to enable automated run directory creation
  • Bug fix: Allow GEOS-Chem Classic History to archive irregular intervals (e.g. a month and a day)
  • Updates for running GEOS-Chem within GEOS
  • Add CH4 pseudo flux diagnostic
  • Add capability to write GEOS-Chem Classic timers to JSON file
  • Update tagged Ox simulation to use archived prod/loss rates from GEOS-Chem and retire Linoz
  • Apply bug fix for dust aciduptake simulation

Updates that will only affect GCHP

  • Add capability to use mass fluxes in advection
  • Switch advection to use total pressure (rather than dry)
  • Add option for driving GCHP with native GEOS meteorological files
  • Add diagnostic for vertical air movement (vertical mass flux)
  • Define a GCHP "Default" diagnostic collection that will archive a small number of commonly-requested diagnostic fields
  • Add capability to read native meteorological data files
  • Fix communicators leak Weiyuan Jiang (GSFC)
  • Fix unintuitive error handling when untemplated file is missing
  • Fix incorrect output file timestamp with 24-hour duration and 1-hour frequency
  • Fix units in FV3 mass flux variable that impacted vertical mass flux diagnostic
  • Move call to setup_wetscav to prevent zero C_H2O used in wet scavening in first timestep
    • This removes differences in wet scavenging when breaking up run
