<div dir="ltr"><div><div>Hi Sorry, I don't know english, but i have one option as solution, i write in spanish <br> <br>Tambien tuve el mismo problema; la solucion fue convertir el archivo grib2 a bin utilizando WGRIB2 (<a href="http://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/wgrib2.tgz">http://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/wgrib2.tgz</a>), luego se utiliza el mismo ctl adaptado a la lectura de un archivo binario, ademas verificar si las variables y niveles corresponden secuencialmente a lo indicado en el CTL (creo que es necesario invertirlo)<br>

I am having no luck getting WAFS GRIB2 files to plot in GrADS and get the "Cannot contour grid - all undefined values" error after many hours of trying seemingly everything. I am downloading the files from:<br>

Then I generate the control files using <a href="http://g2ctl.pl" target="_blank">g2ctl.pl</a> and index files using gribmap.
