Happy new  year all users<br>
I hope your new year is good. I am running wrf in new cluster .<br>
The geogrid.exe runs well with the below warning. How can I overcome this<br>
error? Does this error affect the accuracy of the model runs<br>
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<br>
!  Successful completion of geogrid.        !<br>

Dear wrf-users,<br>
<br>
What is the formula used for calculating surface RH from wrfout file?<br>
<br>
I have already extracted &#39;Q2&#39;, &#39;PSFC&#39; and &#39;T2&#39; variables from wrfout file.<br>
I am just searching for a formula which an convert these parameters to RH<br>
value.<br>
<br>
I am using python to calculate this value.<br>
<br>
Regards<br>
