Categorical Precipitation Types

Post by jboustead » Tue Mar 09, 2021 1:34 pm

Hi All,

I am struggling to output in the following grab2 parameters:

Categorical_Snow_surface
Categorical_Freezing_Rain_surface
Categorical_Ice_Pellets_surface

I am running WRFV4.1.3 compiled using the PGI compiler and using UPPV4 compiled with gfortran to process the wrfout files. The 3 parameters listed above are included in my grib2 output, but when I view the data in a program such as Panoply the scale goes from 0 to 0 and all the values are all zero in the array. I was also having issues getting the Categorical_Rain_surface to output as well, but when I Googled the issue I ran across this post (viewtopic.php?t=9264) so I adjusted the RAINCV and RAINNCV entries in the Registry.EM_COMMON for WRF, WRFPLUS, and WRFDA and then recompiled. I now get data for Categorical_Rain_surface when viewed in Panoply, and the scale looks correct from 0 to 1, but the output for the 3 other parameters is still zero. I do not see any obvious entries (at least obvious to me) variables in the same Registry file to adjust for the Snow, Freezing Rain, and Ice Pellets. I posted in the WRF forum and the suggestion there was that it may be a UPP issue. Would someone have any idea of what I can adjust to get those parameters listed above as well?

Thanks for all the help!

Adding those two variables in the Registry should have fixed the output of precipitation type.

Can you send the specific postcntrl.xml file that you are using?
