Re: Coordiante System Issue - Earth's Radius

I guess I need to look at the netcdf documents... and perhaps ask Nelson 
a similar question. So: What are the standards we're using here?  What's 
the geodetic datums for horizontal and vertial employed here?

Nelson's question sounds a lot like the difference between Clarke 1866 
and GRS80.
