Hello everyone, Merry Christmas and happy new year to you! I want to convert cru.nc files which generated from cruPGI3.x to grib format,but I found the increments of xdef and ydef in the nc files are not 0.5 degree,so how should I edit the ctl file? Any help will be appreciated. ywyang ywyang at lzb.ac.cn 2006-12-29
