Hi,

I have a question about the unit of the POTEVP (potential evaporation) variable in the WRF output.

In WRF V4.1, the unit of POTEVP is m. But in WRF V3.3.1, the unit of POTEVP is w/m^2. Which one is correct? Are there any changes regarding the calculation of POTEVP from WRF V3 to WRF V4?

Thanks in advance!

Xun,
The unit of potevp is m, which is true least since WRFV3.6. I don't think the computation of this variable is changed. It is possible that the definition of its unit is wrong in WRFv3.3.1.
