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 will 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 unify "MET=geosfp" and "MET=merra2" | Will be included in v11-02 |
| Stage 2: Implement custom nested simulations | Enable the compile option "NEST=cu" (custom) to allow custom nested simulations. | Will be included in v11-02 |
| Stage 3: Grid-independent GEOS-Chem classic | Unifying compile options"GRID=xxx" by moving all grid size and related parameters to run-time configuration files. | No specific plan right now. To do be traded off against the nested-GCHP. |
