Hi Roy, it looks like the files are using two different versions of the same grib table. In the wgrib output for some files says: ... center 58 subcenter 0 process 58 Table 2 scan: WE:SN winds(N/S) ... but for some others: ... center 58 subcenter 0 process 58 Table 3 scan: WE:SN winds(N/S) ... So, when the netcdf-JAVA creates the grib collection finds two different variables in the grib records (one per grib table) but those variables resolve in the same name and finally fails to create the dataset. I don't really know how to fix that but a workaround could be create grib files with records containing same tables and then aggregate those files. Cheers!
