Joseph,

Thanks for your reply!!

You're welcome.

I have access to all GFS (AVN) parameters provided in the GRIB files.

I'll have to look to see all the radiation parameters included here, but I
seem to recall it includes just about all of them - i.e., global solar, in
& outgoing IR - I'm not sure about UV. What do you want ? Net radiation
on the horizontal plane ?

If you are looking for very accurate calculations, the GFS probably isn't
the way to go - but if you want something automated, it may be the best you
can do (past the 84 hour period - prior the ETA would probably be better).

Again, what is it you are trying to accomplish/calculate that the GRIB files
don't include ?
