hi everyone
i have a WRF Chem output and i need the temperature values in different layers in the output. however the only variable given is 'perturbation potential temperature(T)' how do i calculate temperatures in different layers using this variable. kindly help me to solve this.
 
HI,
You can obtain potential temperature by

theta = 300 + perturbation potential temperature(T)

Then you can derive temperature from theta and pressure: theta = t *(1000/p)**r/cp
 
hi
could you kindly explain the variables mentioned in the second equation and is there any literature in which i can find the said equation?
 
This is a standard meteorological formula to calculate potential temperature based on T, and vise versa. Please see the details at :
