[Wrf-users] how to cal. MPV?

[wei huang]

HI Users,
I am having WRF forecast files(wrfout_d0* files), saved in 1 hour interval
having total 24 files. I’d like to calculate Moist Potential Vorticity
(MPV)" for every hourly. Is there any function or Script for calculating
"MPV"?
Does anyone know how to do this?
Thanking
wei
