Daniele, I haven't forgotten about your problem. I contacted the French weather service but I didn't get their tables.ugh... At one point you mentioned that you knew what the parameters were for the missing ones. So you could create your own table and read it into the IDV or the Grib package. It's not that difficult, here's 2 urls to help you. http://www.unidata.ucar.edu/software/idv/docs/userguide/data/GribTables.html#grib1 http://www.unidata.ucar.edu/software/netcdf-java/reference/GribTables.html If you make a table, I would appreciate if you send me a copy so I can update my table.
