GEOS-Chem Versions Page

This page includes information about GEOS-Chem 13.2.0 which is currently in development.

Version overview

The following items have been added to GEOS-Chem 13.2.0 since the last benchmark for GEOS-Chem 13.1.0. See also the 13.2.0 milestone on Github.

Feature Contributor(s) Model scope Notes
Updates that will affect full-chemistry simulations
CEDS v2 emissions through 2019 Patrick Campbell (NOAA-ARL)
Melissa Sulprizio (GCST)
Emissions
Updated Yuan/BNU MODIS LAI product (2000-2019) Jenny Fisher (U. Wollongong)
Melissa Sulprizio (GCST)
Emissions
Dry deposition
Improved wet scavenging from Luo et al. (2020) (as option) Gan Luo (Albany)
Fangqun Yu (Albany)
Wet deposition
  • IMPORTANT NOTE: Some small differences at the level of numerical noise (i.e. differences ~1e-6X or ~1e-7X smaller than values) will still occur even when the default wetdep scheme is used. This is because we now better enforce REAL*8 precision by adding _fp or _f8 suffixes to numerical constants where they were lacking in both Luo and default wetdep schemes.
Bug fixes:
  1. Add carbon to species scale factors to AEIC VOC emissions
  2. Fix molecular weight of ethanol (EOH) in species_database.yml
  3. Fix typo in CloudHet function in gckpp_HetRates.F90
Christoph Keller (GMAO)
Viral Shah (Harvard)
Bug fix

Chemistry


Updates that will NOT affect full-chemistry simulations
ObsPack pressure units are now in Pa instead of hPa Eloise Marais (Birmingham) Bug fix
Diagnostics
Add lon & lat bounds to GEOS-Chem Classic History output Chris Holmes (FSU) Diagnostics
Trace metal simulation Junwei Xu (Dalhousie) Specialty simulation
  • See also geoschem/geos-chem Pull request #769
  • Daily data files are very large; we have compressed some.
  • Added trace metal species as a standalone simulation, so as not to burden other simulations with large data I/O
Features only affecting GCHP:

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.

Inventory Type What was added? Directory
CEDS Default CEDS v2 emissions through 2019 HEMCO/CEDS/v2021-06
Yuan-processed MODIS LAI Default Updated BNU v6/Yuan-processed MODIS LAI product (2000-2020) HEMCO/Yuan_XLAI/v2021-06
TRACE_METALS Optional Canadian (CAC) and US (NATA) emissions (2011-2013) for the trace metals specialty simulation HEMCO/TRACE_METALS/v2021-06

1-month benchmarks

This version will require 1-month full-chemistry benchmarks, with and without Luo wet deposition.

1-year benchmarks

This version will require 1-year full-chemistry and transport tracer benchmarks, with and without Luo wet deposition.
