Hi All:<br>
<br>
I was wondering if you could help me with the following:<br>
<br>
I would like to initialize WRF using a constant dz vertical grid: Would you know an easy-quick way to accurately compute sigma for a
given constant dz value using base state environmental data? The problem is that the wrf.input or wrf.out
do not have T and Rho for base state on the sigma grid; they only
have Pb, phb and Mub, which are somewhat more obscure variables.<br>
<br>Also, which
sounding/env WRF uses to compute the horizontally homogeneous base
state remains unclear. Since perturbation variables only matter
during integration the initial env is not that important. However, it
is when trying to get the real (model) Cartesian heights.<br>
<br>
Cheers and thanks for any help you could provide,<br>
<br>
