Hi, all Does anyone know wether or not the Grads can convert the Netcdf data with non-1 scale-factor and non-zero add_offset into the real data automatically, if you use sdfopen command? It seems, but I am not sure. Thanks Bai Xuezhi Ph.D The Center for Ocean-atmospheric Prediction Studies The Florida State University Tel 001-850-644-9138 email bai at coaps.fsu.edu
