Moisture only sounding assimilation in WRF-Var 3.2/3.3

Problems with data in 3DVAR.

Moisture only sounding assimilation in WRF-Var 3.2/3.3

Postby snicholls » Mon Nov 28, 2011 4:48 pm

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,

Hi Stephen
I just went through your post and found the with similar issue I am struggling now. I am wondering whether it is possible to assimilate only Relative humidity data using WRF-Var code ? Could you please suggest me how to do that if you have already resolved your issues.

Thanks
