How to compute relative humidity at 2m

Hi All,

Can anyone provide me with the formula to compute the relative humidity at 2m, given the T2, Q2, and PSFC variables from a WRF output file?

I appreciate any help you can provide.

Hi William,

Thanks for your help. The wrf-python tool does not work for me, so I am wondering if I could get the equation that computes the RH at 2m.
