I have several grib files (forecasts from T+00 to T+96H) which I combine into one grib file via the cat command. grib2ctl runs ok. gribmap gives !!!!!MATCH throughout. However when I try to open the file in grads, I get:</DIV>
<DIV>Open Error: unknown keyword in description file</DIV>
<DIV>The invalid description file record is</DIV>
<DIV>grib</DIV>
<DIV>the data file was not opened.</DIV>
<DIV> </DIV>
<DIV>Is the error in the ctl or in the grib data file?</DIV>
