Hello, I recommend doing the following: For map settings, set you max/min lat lon that you want to use: mpres_at_mpMinLatF                     = 39 mpres_at_mpMaxLatF                     = 45 mpres_at_mpMinLonF                     = -104 mpres_at_mpMaxLonF                     = -95 And comment out the below text: res_at_mpLimitMode = "Corners" ; choose range of map res_at_mpLeftCornerLatF = lat2d(0,0) res_at_mpLeftCornerLonF = lon2d(0,0) res_at_mpRightCornerLatF = lat2d(nlat-1,mlon-1) res_at_mpRightCornerLonF = lon2d(nlat-1,mlon-1) If your strictly following the example on the NCL webpage... (I am more comfortable with the lat/lon min max functions thus why I went with it) For overlay do the following where x is the precip variable that you read in: map    = gsn_csm_map(wks,res) precip  = gsn_csm_contour(wks,(10,:,:),eres) overlay(map,x) I haven't seen your script or your data so I am not 100% sure if this will work or not. Anyways, give it a try and good luck!

However, I am having difficulties zooming in on Nebraska (Latitude 39 N to 45 N and Longitudes 95 W to 104 W). Does anyone out there use  overlay for NARR datasets? Thanks so much. Your help will be much appreciated.   Jane Okalebo PhD student HPRCC, School of Natural Resources University of Nebraska-Lincoln 249 Hardin Hall 3310 Holdrege, Lincoln, Nebraska 68583-0749 U.S.A.   _______________________________________________ ncl-talk mailing list List instructions, subscriber options, unsubscribe: http://mailman.ucar.edu/mailman/listinfo/ncl-talk
