Good morning! I usually run WRF for a whole year to use it for an air dispersion model. When I represent the wind rose at a height of 10 m, I see that the speed that comes out is usually lower than the actual measured speed (around 1 m/s difference) and that did not happen to me before. I've upgraded to WRF 4.2.2 (before 3.4) and I've also upgraded to ds083.3 for gridded data (before ds083.2). I am attaching namelist.wps and namelist.inp in case you can help me. Thank you
