cdo remap
Added by Dennis Shea over 13 years ago
I have been asked a question about the cdo. I can't find the answer in the documentation.
A person used the original fortran SCRIP package to generate a conservative remap file: remap_40962_to_fv0.nc
This remaps from an MPAS unstructured grid to a 288x192 lat/lon grid for post processing purposes.
Currently, there exists IDL and NCL scripts that can use the SCRIP weights contained in
remap_40962_to_fv0.nc to perform the remapping; create plots and netCDF.
Generically, the following could be used:
cdo remap,GRID,remap_40962_to_fv0.nc mpas_1024aq_5e14x1.cam2.h0.0002-01.nc mpas_FV.0002-01.nc
GRID refers to a predefined grid or a CDO grid description
for the finite volume grid. I am not sure how to specify GRID.
What page is this in the documentation?

Hi Dennis,
There are several possibilities to define a horizontal grid in CDO. Here are the most interesting:- predefined grids
- CDO grid description file (ASCII)
- SCRIP grid description file (netCDF)
- grid description from all supported data files (GRIB or netCDF)
The documentation can be found in the CDO Users Guide on page 10-13 (http://code.zmaw.de/files/cdo/html/1.4.7/cdo.pdf).
Best regards,
Uwe
