Re: mask not adjusted with the contour

Hi,

The "mask()" function in the call to "gsn_csm_contour_map_ce()" is returning an array that does not have the coordinate values associated with it. A solution (thanks to Dave Brown) is to break out the call to the mask function, and assign the results back to the variable "sst", retaining the coordinate association:

sst = mask(sst, maskme, 0)
plot =gsn_csm_contour_map_ce(wks, sst(0,:,:), rest)

Also, the "0" in the mask function is for land, "1" is for oceans.

Hope that helps…
Rick
