Hi,<br><br>FNL files can either be in grib1 or grib2 format. You can tell the difference<br>by running wgrib (a grib1 utility) or wgrib2 (a grib2 untility) on the file. You'll<br>know that you've found the right format by getting nice inventory.<br>
<br>For grib1 analysis files, you use<br><br> <a href="http://grib2ctl.pl">grib2ctl.pl</a> gribfile >gribfile.ctl<br> gribmap -0 -i gribfile.ctl<br><br>For grib1 forecast files, you use<br><br> grib2ctl -verf gribfile >gribfile.ctl<br>
gribmap -i gribfile.ctl<br><br>* These instructions differ from the previous answer *<br><br>For grib2 analysis files, you use<br><br> g2ctl -0 gribfile >gribfile.ctl<br> gribmap -0 -i gribfile.ctl<br><br>For grib2 forecast files, you use<br>
<br> g2ctl gribfile >gribfile.ctl<br> gribmap -i gribfile.ctl<br><br>Note that g2ctl is consistent with gribmap in its use of the -0 and -b flags.. <br><br>For Windows, you have to use "perl <a href="http://grib2ctl.pl">grib2ctl.pl</a>" and "perl g2ctl".<br>
<br>In order for <a href="http://grib2ctl.pl">grib2ctl.pl</a> to work, wgrib must be compiled and placed on your path.<br>In order for g2ctl to work, wgrib2 must be compiled and placed on your path.<br><br> Wesley Ebisuzaki<br>
