Hi,<br><br>After ran the data assimilation using da_wrfvar.exe, how can i verify wheather the observation was assimilated with the first guess ?<br>I use the NCL script from <br><a href="http://www.mmm.ucar.edu/wrf/OnLineTutorial/Graphics/NCL/Examples/LEVELS_MODEL/wrf_EtaLevels.htm">http://www.mmm.ucar.edu/wrf/OnLineTutorial/Graphics/NCL/Examples/LEVELS_MODEL/wrf_EtaLevels.htm</a><br>
to plot the assimilated data and first guess, wrfvar_output and fg respectively, but i see the resulting graph seem have no different ..<br><br>Thank you<br><br>Regards,<br>Patrick<br>
