Description

I found that if I use the Ferrier Microphysics Scheme,DBZ cannot be correctly outputed in higher level(e.g. >8km or <150mb).

Here is the example wrfout file,and the files output from UPP(Pressure level).

Research direction

Download the linked example wrfout file and UPP pressure-level output files first, then compare DBZ values from the Ferrier Microphysics Scheme above 8 km or below 150 mb. Trace the relevant diagnostic or interpolation entry point in wrf-python and define done as correctly outputting DBZ at those higher levels.
