Re: Polar stereographic scatter plot

Generically, something like the following.

   wks = gsn_open_wks("ps","mjackson") ; open a graphic wks
   res = True
   res@gsnPolar = "NH"
   res@gsnFrame = False
   res@gsnDraw = False
   plot = gsn_csm_map_polar(wks,res ) ; draw polar map

; http://www.ncl.ucar.edu/Applications/polyg.shtml
; See Examples 3 and 8

    polyres = True
    polyres@gsMarkerIndex = 16 ; polymarker style
    polyres@gsMarkerSizeF = 5. ; polymarker size

    dum1 = gsn_add_polymarker(wks,plot,glon ,glat ,polyres)
    draw(plot)

   frame(wks)
