[Wrf-users] guidance and advice on using observation nudge in WRF

[Dr. Robert Pasken 300a]

I'd also like a little guidance on obs nudging as well. I have dropsonde 
data that I would like to use in WRF simulations. I have converted the 
data appropriately and the WRF output shows that the dropsonde data is 
being read into the model, but there is zero (0, nadda, zip) difference 
between the nudge and non-nudged runs as shown by ncl plots of the 
differences between the wrfout files
