Hi Maryam,<br>
<br>
I'm a little bit confused about your script. The AFR-44 data must
have time, lat and lon dimensions so the complete defining and
assigning of time, lat and lon to the variable pre is not needed.
You can read them directly <br>
<br>
<tt>time = f->time</tt><tt><br>
</tt><tt>lat = f->lat</tt><tt><br>
</tt><tt>lon = f->lon</tt><br>
<br>
After creating a contour plot of variable pre there is an exit call
and NCL will stop directly without executing the rest of your
script. But looking at the rest why are you overwriting your
variable pre with random data? You will use the random data to
define the new variable data!??<br>
<br>
By the way, if you are running NCL 6.3.0 you do not need to load the
gsn_code.ncl, gsn_csm.ncl and contributed.ncl libraries anymore.<br>
<br>
Bye,<br>
Karin<br>
