[Wrf-users] Pseudo-Single Obs Test in WRFDA

I am using WRFDA and WRF-ARW version 3.3.1, and have generated a  
background error covariance file be.dat for my specific season and  
model grid, and am trying to determine if I need to tune, etc, because  
the answers that I'm getting are quite unreasonable.  For this  
purpose, I'm running a single observation test, and seem to get  
reasonable values for wind observations.  However, when I try to put  
in a temperature observation, I don't get any increment.  The  
difference between the first guess and the analysis is zero.  Any ideas?
