The ARWpost software also includes utilities (look in the util subdirectory) that can make a .ctl file from your WRF history dump file so you can view the raw output in Grads without first post-processing it.  It would probably take you less time if you go this route, but you will have to manually compute relative humidity in Grads then.  It isn&#39;t required of you to compile or run ARWpost to use these utilities.<div>

plotting onto native grid is the right way to go, but grads doesnt have a better way to give you the map on native grid yet. </p>

&gt; Apparently WRF does not give humidity and temperature at different<br>&gt; levels, except T2, temperature at 2m.<br>&gt; I have to calculate rh at each level from<br>&gt; es = 6.112*EXP(17.67*(t-273.15)/(t-29.65))<br>

&gt; e = qv * p/100./(qv + 0.622)<br>&gt; rh = e/es<br>&gt; But before that I have to get the temperature from potential temperature using<br>&gt; temperature = (T2 + 300)
 [(P/P0) ^ (R/Cp)]<br>&gt; I was wondering if there are users who visualise WRF output in grads,<br>&gt; and if they have scripts for the above conversions.<br>&gt; Thanks<br>&gt; Zilore<br>&gt; On Wed, Jun 13, 2012 at 1:27 AM,  &lt;<a>gradsusr-request@gradsusr.org</a>&gt; wrote:<br>
