I need your help or suggestions to overcome a problem. I have WRF output from two model runs with same horizontal and vertical resolutions. I have two ctl files for this purpose with corresponding dat files for them. For both of these outputs, I have xdef, ydef, zdef and tdef same for both the files. However, the number of variables are different. One contains 166 variables and other 123. Since the model was tuned to produce more variables in the output file in the earlier case, the number of variables are more. However, in the later case it was not tuned to do so. On the other hand, they do produce same diagnostics after post processing. </div>
