Have you found a way to do this yet?<br>
<br>
Here is a section of GrADS script code that may be helpful (from
Vaughan Phillips):<br>
<br>
---<br>
'open /home/vtp/GCSS2_WRF/test/eh_squall2d_x/TOGA_NEW/ifamean.ctlt'<br>
'set z 1'<br>
'set x 1'<br>
'set y 1'<br>
'set t 1 960'<br>
'define prec = prec'<br>
'define pobs = tloop(sum(prec,t=393,t+0))'<br>
'set t 393 441'<br>
'define pob = pobs'<br>
'd pob'<br>
<br>
'draw xlab time (days)'<br>
'draw ylab P (mm)'<br>
'draw title \ ACCUMULATED PRECIPITATION' <br>
'close 1'<br>
'cbar_l -t "WRF" "LAN" "OBS" -p'<br>
'print'<br>
'disable print'<br>

<pre wrap="">Hello everyone,
I have a question about setting up a loop. I want to
generate a 24 hour accumulated precipitation total
forecast from the WRF model. For example, if I had a
36 hour forecast starting at 00Z August 12, I want to
look at the last 24 hours of that forecast (12Z August
22 - 12Z August 23).
I know that my loop should increment with the forecast
interval (every 3 hours). Also, I know that, within
this loop precipitation needs to be summed up. I've
forgotten exactly how to set up such a loop. Thanks in
advance for any help that anyone might be able to
offer.
Aaron
