I want to assimilate radar data, da_wrf.exe success but it didn't seem to work

[jjvinsion]

I want to assimilate radar basic reflectivity data to WRF. I wrote the ob.radar, then run da_wrf.exe. It shows that radar assimilation successed in rsl.out.0000 but it didn't seem to work because the parameter fields (like U, V) are the same before and after the assimilation. I don't know how to solve this problem. Pls help me, thank u.

It might be the error variance column. (4th and 7th columns in data record).
I don't think setting them with the default value(-888888) will work.

I am reading the source code for ./da_wrfvar.exe to solve my problem while happen to meet the part that probaly solve your problem.
Setting the error value to missing_r leads the qc(quality control) to missing data, which makes all of your data invalid.
