Hi Luiz We can make a guess on "what's happening" as follows: It's likely that the fields in file OCCAM_1degree.nc were created using r8 (double precision). The problem is that the NetCDF library is unable to convert to 32-bit. Although this does not happen in our system at GFDL, this may happen on other system like yours. This is why you see only NaN
