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)
