Dear All,<br>
<br>
I have hundreds of thousands of daily model data in grib format<br>
and I would like to create monthly averages of that. I know I could<br>
do that with a grads script, but it would take too much time.<br>
<br>
If I had netCDF files, there are tools like NCO that allows one to<br>
add, subtract, merge, average, etc.. a bunch of .nc files<br>
as long as they share the same variables.<br>
<br>
Is there something like that for grib files?<br>
