This page includes information about benchmark simulations comparing GEOS-FP 5.22 meteorology to GEOS-FP 5.25 meteorology using GEOS-Chem 12.8.0.
Major update to GEOS-FP meteorology
NASA’s Global Modeling and Assimilation Office (GMAO) announced a major update to the GEOS-FP (“Forward-processing”) data stream. The switchover to GEOS-FP version 5.25.1 occurred on January 30, 2020. This new version contains the following updates to the GCM:
- New convection scheme: The RAS convection scheme used to date has now been replaced with Grell & Freitas deep convection plus Park & Bretherton shallow convection.
- New radiation scheme: The Chou-Suarez shortwave model has been replaced by RRTMG.
For more details, please read the full announcement about the update to GEOS-FP 5.25.1. Because the GEOS-FP meteorological product is an operational dataset, system changes and updates such as these are made at regular intervals. This ensures that the GEOS-FP data product reflects the state of the science. If you use GEOS-FP met fields to drive GEOS-Chem simulations for model dates after January 30, 2020, note that the convection and radiation variables might show substantial differences with respect to prior dates.
The benchmark simulations below can be used to assess the impacts of this GEOS-FP system update.
If you would prefer using a meteorology product that does not contain any system changes, then consider using the GMAO MERRA-2 reanalysis product. MERRA-2 has a native resolution of 0.5 degree x 0.625 degree native resolution, and is generated with a “frozen” assimilation system based on the GEOS GCM version 5.12.4. There are more than 30 years of assimilated MERRA-2 data available (~1980-present) for you to use with GEOS-Chem.
