<p class="MsoNormal">Dear NCL-users<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m encountering a strange behavior regarding the wrf_map_resources function in NCL’s WRFUserARW.ncl file. I’m trying to plot precipitation field from a wrfout file (tot_rain_gsn_d01.ncl). Map projection is Lat/Lon as you can see in ncdump.txt
while a rotated grid is assumed. The domain is the EURO-CORDEX domain.<o:p></o:p></p>
<p class="MsoNormal">Just for clarification, I want to plot in native grid, for that I enabled the options below, <o:p></o:p></p>
<p class="MsoNormal">res@tfDoNDCOverlay = True<o:p></o:p></p>
<p class="MsoNormal">res@gsnAddCyclic = False<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">NCL version is 6.3.0<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I use the default WRFUserARW.ncl file, I get the following error,<o:p></o:p></p>
<p class="MsoNormal">(0) gsn_csm_map_ce: Fatal: The resources mpMinLonF/mpLeftCornerLonF must be less than the resources mpMaxLonF/mpRightCornerLonF.<o:p></o:p></p>
<p class="MsoNormal">(0) Execution halted,<o:p></o:p></p>
<p class="MsoNormal">which as I understand is due to this information,<o:p></o:p></p>
<p class="MsoNormal"> mpRightCornerLonF : 68.72884<o:p></o:p></p>
<p class="MsoNormal"> mpRightCornerLatF : 66.90226<o:p></o:p></p>
<p class="MsoNormal"> mpLeftCornerLonF : 349.4225<o:p></o:p></p>
<p class="MsoNormal"> mpLeftCornerLatF : 20.57643<o:p></o:p></p>
<p class="MsoNormal"> mpLimitMode : Corners<o:p></o:p></p>
<p class="MsoNormal">upon printing wrf_map_resources.<o:p></o:p></p>
<p class="MsoNormal">The error is eliminated when I set mpLeftCornerLonF = min(pr@lon2d), as you can see in tot_rain_gsn_d01.ncl. By doing this I get the image in d01_rain_total_minlat.png file.<o:p></o:p></p>
<p class="MsoNormal">I tried to play around with the options in WRFUserARW.ncl file, in the section where wrf_map_resources function is located with no success. For example when I disable the mpCenterRotF option, I get the d01_rain_total_NOmpCenterRotF.png
file. Moreover, when I add the mpCenterLatF option while turning on again the mpCenterRotF option, I get the d01_rain_total_mpCenterRotF-mpCenterLatF.png file.<o:p></o:p></p>
<p class="MsoNormal">What am I missing? Maybe some additional code is required?<o:p></o:p></p>
<p class="MsoNormal">Any help is appreciated.<o:p></o:p></p>
