Overview
FlexGrid is a new functionality in GEOS-Chem v11-02 to unify all metfield I/O routines by HEMCO.
HEMCO's interface and regridding&cropping capability allow users to
- Set up a nested simulation over any custom domains without changing model's source code.
- Explicitly control each meteorological variables in configuration files to perform various experiments (an interface resembling GCHP).
FlexGrid implementation plan
The table below shows the implementation plan for FlexGrid:
Stage | Detail | Status |
---|---|---|
Stage 1: Read metfields by HEMCO | Enable the compile option "MET=flexgrid" to read any NetCDF-format metfields through HEMCO. This unifies "MET=geosfp" and "MET=merra2" |
|
Stage 2: Implement custom nested simulations | Enable the compile option "NEST=cu" (custom) to allow custom nested simulations. |
|
Stage 3: Grid-independent GEOS-Chem classic | Unify compile options "GRID=xxx" by moving all grid size parameters and resolution-dependent parameters to run-time configuration files. | No specific plan right now. Need to be traded off against the nested-GCHP development. |
