Hi john, 
I want to know how I have to give options for copygb. 

here s what I am trying. 

./copygb.exe -g "${grid}" -x     WRFPRS_d01.002  copygb2013052100-WRFPRS_d01.002
./copygb.exe -g "${grid}" -x     WRFPRS_d01.003  copygb2013052100-WRFPRS_d01.003

How should I give kgds and kpds options.

Subject: query reg the copygb.
From: Randy Bullock

Hi Geeta -

John's on vacation this week, but I'll give this a shot.

Somewhat to my surprise, I wasn't able to find much on the usage of
copygb,
but a co-worker found these two links that have information on copygb
usage:

http://www.dtcenter.org/met/users/support/online_tutorial/METv4.0/copygb/copygb.txt

Starting on slide 25, there is good info here
http://www2.mmm.ucar.edu/wrf/users/tutorial/201407/Wednesday/3_smith_upp.pdf

If those links don't give the info you need, I suggest emailing wrf-
help,
since they're the ones who wrote copygb.

Hope this helps!

Randy Bullock
