Jim,
Could you please clarify how to represent data which contain bands
with multiple spatial resolutions using you scheme? I am thinking of
MODIS data:
http://en.wikipedia.org/wiki/Moderate-Resolution_Imaging_Spectroradiometer#MODIS_Bands
As you can see, not all the bands have same spatial resolution (or
spatial dimensions), even though all of them have same units. Could
we even store all the bands in the same variable?
I think multiple resolutions in same variable would be difficult and
impracticable,
the CF conventions for defining Projections, analytic or lat/lon,
don't work like
this. You'd probably have to define another dimension to index the
different
resolutions for the data, lon and lat variables. I would think this
would be
pretty messy.

Correct, you need seperate variables for different resolutions. However,
theres no problem with having multiple coordinate systems in the same
file. So if you chose, you would create multiple groups of variables,
each group with their own coordinates.
