Hi everyone,
<div><br>
</div>
<div>I've emailed about this before, but will those of you who have a chance try to run a pseudo-single observation test (PSOT) with WRFDA by setting the variables in your namelist as:</div>
<div><br>
</div>
<div>
<div>&wrfvar15</div>
<div>num_pseudo = 0,</div>
<div>pseudo_x = 10,</div>
<div>pseudo_y = 10,</div>
<div>pseudo_z = 10,</div>
<div>pseudo_val = 1.0,</div>
<div>pseudo_err = 1.0,</div>
</div>
<div><br>
</div>
<div>
<div>&wrfvar19</div>
<div>pseudo_var = "u"</div>
</div>
<div><br>
</div>
<div>You'll need a wrfout file as a first guess and a background error file be.dat. What I'm curious about is whether you get a response when you change the "u" to "v", "t" or "q". I get a reasonable response when I set the variable to "u", but none at all
when I set it to "v", "t" or "q". The output shows that the observation is seen by WRFDA, but it doesn't contribute to the cost function. If you have a chance, please let me know what you get when you give this a try. I'm doing some work that is pretty
heavily dependent on the length scales in the background error covariance, so I need this feature to work.</div>
