My experience with grib2 files is to use convgrb to convert them to grib1 files, then use <a href="http://grib2ctl.pl">grib2ctl.pl</a> to get a control file for each converted grib1 file. You can do that using a C-shell loop. Once you do that, you can use a while loop in a Grads script (not at the command prompt), to open each individual file and print the data to a text file using <a href="http://cookbooks.opengrads.org/index.php?title=Recipe-002:_Saving_GrADS_variable_data_to_a_text_file">fprintf</a> .<br>
