All,
I am attempting to isolate the impact of sounding moisture alone on a series of WRF 3.2 model runs. Currently, if I assimilate sounding data into WRF-Var 3.2 with only dewpoint data, all my observations are rejected by obsproc.exe. I would presume this is likely because WRF uses RH which would itself requires temperature? That said is there any way to either modify WRF-Var to assimilate only dewpoint data or to significantly curtail the impact of temperature data by reducing its weight.
Thanks,
