Grib.pm allows the user to read files in the grib FORM FM 92-IX Ext. GRIB into perl PDL - it may not read all possible grib format combinations. If you want to use this module you'll need to have some understanding of the format as the module refers to section octet numbers rather than trying to name all of the fields. The manual is available on line at: http://www.wmo.ch/web/www/reports/Guide-binary-2.html Prerequisites - You need to have the perl PDL module installed. http://pdl.perl.org Build and Install: $ zcat PDL-IO-Grib-xx.tar.gz | tar xf - $ cd PDL-IO-Grib-xx $ perl Makefile.pl $ make $ make install Changes / enhancements you plan to make in the future: Need to expand the list of possible grib flavors it can read. ECMWF, NCEP, and DWD all have slight variations on the theme. It would be nice if it could write too. New in this version (1.20) Added the script GribView.pl which can be used to view the Grib header data and with TriD or PGPLOT to plot simple contours of the data. GribView requires Tk and Tk::FileDialog Added partial write capability including the ability to update a pre-existing file. Uses xs and some code from wgrib to decode data. Stores all section information in pdl format and only decodes on demand.
