<br>
I am trying to plot WRF-ARW data using gsn_csm_contour_map. I have <br>
followed the script in <br>
<a href="https://www.ncl.ucar.edu/Applications/wrfgsn.shtml" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Applications/wrfgsn.shtml</a>.<br>
<br>
But unfortunately I am not getting the contours. I am attaching the <br>
script I used and the plot I got.<br>________________________________________________________________________-<br>
d1 = addfile("/home/anie/Documents/WRF_Chem/EXP01/<a href="http://wrfout_d01.nc" rel="noreferrer" target="_blank">wrfout_d01.nc</a>", "r")<br>
<br>
it = 0 ; first time step<br>
hgt = wrf_user_getvar(d1,"HGT",it) ; Terrain elevation<br>
hgt@lat2d = wrf_user_getvar(d1,"XLAT",it) ; latitude/longitude<br>
hgt@lon2d = wrf_user_getvar(d1,"XLONG",it) ; required for plotting<br>
<br>
wks = gsn_open_wks("png","wrf_gsn")<br>
<br>
;---Set some basic plot options<br>
res = True<br>
<br>
res@gsnMaximize = True ; maximize plot in frame<br>
<br>
; res@tiMainString = filename<br>
<br>
res@cnFillOn = True<br>
res@cnFillPalette = "OceanLakeLandSnow"<br>
res@cnLinesOn = False<br>
<br>
res@mpProjection = "CylindricalEquidistant" ; The default<br>
res@mpDataBaseVersion = "MediumRes"<br>
<br>
res@gsnAddCyclic = False<br>
<br>
;---Zoom in on plot<br>
res@mpMinLatF = min(hgt@lat2d)<br>
res@mpMaxLatF = max(hgt@lat2d)<br>
res@mpMinLonF = min(hgt@lon2d)<br>
res@mpMaxLonF = max(hgt@lon2d)<br>
<br>
contour = gsn_csm_contour_map(wks,hgt,res)<br>

Kindly help me identify the issue.<br>
<br>
Looking forward to any kind of help.<br>
<br>
Thank you<br>
