Wesley,
thanks very much!
I know you rather would like to help me walk than just give me wheels,
but I'd rather have a copy of your ctl file, that plotted
the land sea mask.
(just checked once more before crying on your sholder)
Aha! I had a copy of wgrib in the grads installation, that was picked
up sooner than the new wgrib!
SWEET!
All I need now is to convince chaps at ECMWF to supply
Grads 1.9 ++ on the Aix box.
Last time we looked, (2 weeks ago)
we could not find one that is compatible.
Can you find one for AIX 2-5 , please?
Thank you very much!
This is excellent news.
Grads on reduced grib files! Marvellous.
Thanks again,
Bernd.
