Re: Error trying to plot a MODIS data

Oluseun,

Brian indicated below what the problem likely is: you are probably trying to plot a 3D variable, and gsn_csm_contour_xxxx only accepts 1D or 2D arrays. He also indicated how to fix this. Did you give this a try?

As a side: the reason the error message mentions "gsn_csm_map_other" is because the map projection was set to "Orthographic". Under the hood, this function is called by gsn_csm_contour_map to generate the plot. When you do a cylindrical equidistant plot, it uses "gsn_csm_contour_map_ce" under the hood. "gsn_csm_contour_map_polar" is used for polar stereographic plots.
