Hi Wilson, The grib library deals with the the very low levels of decoding Grib files that has many, many details that are confusing and time consuming to understand. We suggest using the netcdf-java library that handles the details and arranges the data in a manner that you mentioned. Here's a tutorial to help get you get started: http://www.unidata.ucar.edu/software/netcdf-java/tutorial/ I would look at GridDatatype, NetcdfFile, and NetcdfDatasets Documentation at: http://www.unidata.ucar.edu/software/netcdf-java/documentation.htm Here's a reference to support question with coding examples that should help also: http://www.unidata.ucar.edu/mailing_lists/archives/netcdf-java/2009/msg00235.html Robb....
