Regridding in GEOS-Chem
NOTE: Page under construction!
On this page, we shall describe how GEOS-Chem regrids data from one resolution to another.
The MAP_A2A algorithm
In GEOS-Chem v9-01-03, the driver routine DO_REGRID_A2A now reads the grid input information (i.e. longitude edges and sines of latitude edges) from netCDF files. This replaces the original implementation, which read from ASCII files.
At present, the MAP_A2A algorithm executes only on a single processor.
