Extending GRIB area definition

Added by Nigella Sanders over 6 years ago

I have a GRIB file defined on a limited area enclosed by lat1,lat2,lon1 and lon2.
Is there any way to extend there boundaries to make it global?
Data would be still defined on the original box and aditional area would be MISSING.
Just like in this photorealistic :) example:

Try the CDO operator remapnn. The extrapolation feature needs to be disabled by the environment variable REMAP_EXTRAPOLATE=off:

export REMAP_EXTRAPOLATE=off
cdo remapnn,<targetgrid>  infile  outfile
