    plotting GEOG files

    How can we visualise the static geographical data (e.g., one landuse_30s file in GEOG)? Any matlab/python code available? Help is solicited ASAP. I am attaching a sample file for your reference. regards, V. Hazra

    WPS4.3 different *met_em* files have different number of metgrid levels

    I used era5 data for preprocessing, but the number of met files varies from time to time. It was 38 layers at 00 UTC, but it became 27 layers at 03 UTC, which made it unable to achieve real success because of the difference num _ metgrid _ levels.

    Small HGT error when running geogrid on high-res dataset

    Hello, I downloaded USGS 1/3" topographic data for some simulations I am working on. I was able to stitch together multiple tiles into my own dataset according to WRF guidelines (i.e. the whole 0xxxx-0xxxx.0yyyy-0yyyy naming conventions), and can successfully run geogrid.exe and generate maps...

    Difference between LAI(ALBEDO) in WRF output and in WPS output

    Dear WRF Community, I have a question on substitution of ALB/LAI in WRF V3.9 : The amounts of LAI and ALBEDO in WRF output and that in WPS output are different, although I set sst_update=1 , usemonalb=true,rdlai2d = true and auxinput4_inname = 'wrflowinp_d<domain>' in namelist.input. . Thanks...
