[ncl-talk] map of Greenland

Hi Erik,

I've wrestled with this one quite a bit (and cursed that most of my 
research is in polar latitudes).  Unfortunately, I don't have a simple, 
self-contained example since the "plot Greenland" part is embedded in a 
much bigger, quite specific-to-my-needs script. However, the following 
variables and resources should help you get started.  Some adjustment 
may still be needed to get exactly what you want.
minLon = -60
maxLon = -25
minLat = 58
maxLat = 86.5
res at gsnPolar = "NH"
res at gsnTickMarksOn = False
res at mpProjection = "LambertConformal"    ; I like this rather than 
stereographic
res at mpLambertMeridianF = (minLon + maxLon) / 2
res at mpLimitMode = "LatLon"
res at mpMinLatF = minLat
res at mpMaxLatF = maxLat
res at mpMinLonF = minLon
res at mpMaxLonF = maxLon

I then use gsn_csm_contour_map since I'm actually plotting data. 
gsn_csm_map might be all you need if you just want a map.

If I remember correctly, it's hard to get good automatic lat/lon labels 
so I just don't bother (especially since I usually end up paneling lots 
of these together and I don't need the extra text). But I think the NCL 
site has some examples for adding lat/lon manually if you need it.

Good luck!
Dave
