[Wrf-users] Re: WPP and copygb

[teresa tiberi]

Hello Huiya,

yes,I'm interested to plot nested domain.in the plots you can find the
south Italy a bit shifted to west.
I send you temperature at 2m and landsfc, and you can find the mail
sended to wrf-users below.

thans in advance

best regards

Teresa

>From your copy_nav.txt, it looks like you're trying to plot the
nested domain, is that true?
