[ncl-talk] ESMF_regrid_gen_weights error

[Dave Allured - NOAA Affiliate]

I do not think this is a direct constraint of the ESMF routines.  The
primary error message concerns the creation of a Netcdf file for regridding
weights.  This message is typical for trying to create a file variable that
exceeds the 2 Gb limit for netcdf-3 and netcdf-4 classic formats.  Look for
an option to specify the full netcdf-4 format (not "netcdf-4 classic") when
creating an ESMF weights file.  I am not an ESMF expert; you will need to
look this up for yourself.
