Geeta,
It may be because the longitude range is (-179.875,179.875); try to use
lon, lat to define obs variables within longitude range (0.,360.).
In your GrADS script, try this:
'open rfaccum.ctl'
'set lon 0.125 359.875'
'set lat -49.875 49.875'
'set z 1' ;* just to be sure
'set t 1' ;* just to be sure
'define rf1=data(t=1)'
...
'printim figure1.gif'
'set gxout fwrite'
'set lon 0.125 359.875' ;* just to be sure
'set lat -49.875 49.875' ;* just to be sure
'set z 1' ;* just to be sure
'set t 1' ;* just to be sure
'd rf'
'disable fwrite'
Then, make a GrADS ctl file Obs22apr2011.ctl for Obs22apr2011.bin which
uses the parameters:
XDEF 1440 LINEAR 0.125 0.25
YDEF 400 LINEAR -49.875 0.25
ZDEF 1 LEVELS 1000
TDEF 1 LINEAR 00z22apr2011 1dy
now for Obs22apr2011.ctl you can use x, y coordinates...
'open Obs22apr2011.ctl'
'set gxout shaded'
'set x 1 1440'
'set y 1 400'
'set z 1'
'set t 1'
'd data'
Hope this helps,
Chuck

Hi,
I would like to do the same calculation shown below, only over US land
region. Could someone help me with mask file ? or else explain me how to
use basemap shape file to mask the ocean. Is that possible to do?
An example of taking an area average of data only over land, given a mask
grid:
ave(aave(maskout(p,mask.3(t=1)),x=1,x=72,y=1,y=46),t=1,t=30)
say result
Thanks,
Adv

Hello all:
I have a question:
I downloaded the new Great Lakes Wave GRIB files today the same way I
always do, and then I used wgrib2 to prepare the data for using in GrADS
(like I've been doing every day for years), which all went fine. But
when trying to open the files in GrADS I get the error "SDF file has no
discernable X coordinate". I've never had this problem with the old GLW
data files, what's different now?... I know the file names and
resolution is different, but what about the data itself?
If anybody can help me I'd really appreciate it.
Regards,
Bill
