[Wrf-users] plot surface pressure in WRF

[Eric Altshuler]

Hi Tabish, 


Yes, you are correct. Total pressure = P + PB.

Hi 


I want to plot pressure at various model levels (50 in my case). I notice that there are 2 variables related to pressure in WRF: P (perturbation pressure) and PB (base state pressure). 


Do I need to add both the variables to obtain the total pressure at a given vertical level? 


Thanks in advance
