We are working on it, but for these files, we would need
to have the information to relate sigma to a vertical
pressure or height coordinate.  The netCDF CF convention
has ways of specifying this:

and that is the path we are taking to support sigma
(and other dimensionless) vertical coordinates at this
point.
