Familiarize Yourself with the Data

The more you know about the data you are using, the easier it will be to understand the errors when things go wrong. To display information regarding GRIB data, there are various tools available.

WPS Tools

In the WPS/util directory there are two utilities to view GRIB data - g1print.exe and g2print.exe (for GRIB1 and GRIB2 data). These utilities print a listing of the fields, levels, and dates of the data in the file.

Other Tools

The wgrib tools are also very handy to view data information from GRIB files.

     -wgrib2: (http://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/)

The grib2ctl tool can be used to display GRIB1 data in GrADS.
