Hi Paula,
I don't know if you want to do this or not, you can also subset the data
to increase the plotting speed and decrease the workstation size
requirements. Change this:
resH@sfYArray=lats_Huron
resH@sfXArray=lons_Huron
plot_Huron=gsn_csm_contour(wks,b_Huron,resH)
to this:
resH@sfYArray=lats_Huron(::4)
resH@sfXArray=lons_Huron(::4)
plot_Huron=gsn_csm_contour(wks,b_Huron(::4,::4),resH)
(and do the same thing for the Lake Michigan section of code)
That will plot every 4th grid point. You can try other numbers, 2, 3 or
5 for instance..
Results are attached showing every 4th grid point plotted.
