Aloha Grads Users, <br><br>I am trying to create some difference plots for my WRF model runs.� One run starts at 0Z and has no feedback, the other starts at 6Z and has feedback on.� The grids have the same dimensions and the .ctl files are almost identical other than the time differences.� If I open up my domain and use this code to make a difference plot, it works without a problem (for my 4 outer grids):<br>
<b><i>time=12 </i><br></b>*for rainnc.2, add 6 to the time because it started 6 hours earlier<b><br>'d rainnc.1(t='<i>time</i>')-rainnc.2(t='<i>time+6</i>')'</b><br clear="all"><br>I am interested only in a small part of this domain (over the island of Oahu).� So I try to zoom in a bit and I get an error:<br>
<b>'c'<br></b>* set the lat and lon to be zoomed in on oahu<b><br>'set lat 21.2211 21.9438' <br>'set lon -158.298 -157.521'<br>'d rainnc.1(t='<i>time</i>')-rainnc.2(t='<i>time+6</i>')'</b><br>
Here is the error:<br>Error in gagchk: axis values are not all the same<br>Operation error:� Incompatable grids <br>� Error ocurred at column 30<br>DISPLAY error:� Invalid expression <br>� Expression = rainnc.1(t=12)-rainnc.2(t=18)<br>
<br>On my high resolution 166m grid which has the lat and lon dimensions from above, the difference plot code that works for my four outer grids does not work.� It gives me the same error.� Do I need to set the lat/lon dimensions differently for the second file?� Is there a way to fix this error?� <br>
