Hi Roni,
The easiest way to do this is to use a Lambert Conformal projection plot:
http://www.ncl.ucar.edu/Applications/lcmask.shtml
I would set the following resources:
sres@mpMinLonF = 90.
sres@mpMaxLonF = -90.
sres@mpMinLatF = 20.
sres@mpMaxLatF = 85.
sres@mpProjection="LambertConformal"
sres@tmBorderThicknessF = 3.
sres@gsnMaskLambertConformal = True
If you wanted to draw a rectangular box around the plot, this can be
done by using gsn_polyline_ndc:
http://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_polyline_ndc.shtml
You could try to draw a polar stereographic plot and mask the top half
of it with gsn_polygon_ndc:
http://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_polygon_ndc.shtml
But this method could get complicated especially if you want to use
gsn_panel.
Good luck,
Adam
