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.
Cheers, WS
