I've placed a copy of a file getting the same error at: http://fuelberg.met.fsu.edu/pub/wsession/idv_test.nc This file contains two versions of the extinction 3D field - one using an arbitrary vertical height coordinate and one using the correct model sigma coordinates. Attempting to plot a 3D isosurface with the sigma version produces the error.
