[ncl-talk] issue plotting netCDF4 file

[David Brown]

Hi Neil,
The precip variable in this file contains NaNs. They must be replaced for
NCL's plotting functions to work properly.

Add the following to your code following after reading the precip variable:

cpc_precip = cpc_file->precip(:,:)
if (any(isnan_ieee(cpc_precip))) then
        replace_ieeenan(cpc_precip,cpc_precip at _FillValue,0)
end if
