Thank you for the reply.
I added:
istatus = nf90_def_var(ncid,"lat", nf90_float, ila, ilat )
write (6,*) trim(nf90_strerror(istatus))
i*status = nf90_put_att(ncid, ilat, 'units', 'degrees_north')*
istatus = nf90_def_var(ncid,"lon", nf90_float, ilo, ilon )
write (6,*) trim(nf90_strerror(istatus))
*istatus = nf90_put_att(ncid, ilon, 'units', 'degrees_east')*
To give units to the latitude and longitude. Now I have a new error:
ga-> sdfopen foo.nc
Scanning self-describing file: foo.nc
SDF file has no discernable time coordinate -- using default values.
gadsdf: SDF file does not have any non-coordinate variables.
What does that mean?
