Hello, I'm not a weather person per se (physicist) and am trying to do some basic WRF runs to generate "realistic" radar returns for a separate simulation. I did find the vapor_wrf Python code to compute dBZ. I ran the basic em_quarter_ss case to get something to start with. I understand the X and Y grids are Cartesian and DX and DY give the spacing. The Z coordinate is a bit tougher since I'm not well versed in pressure level jargon. To generate simulated 3-D radar returns I need to map those Z coordinates to real altitude. It appears some algorithm using DZBOT, DZSTRETCH_? and perhaps some other variables is required. Any tips? Thanks!
