Re: Question about GODAE flavor of NetCDF

Murray,
	ncBrowse is working properly.  The difficulty is that the GODAE live 
access server is creating a netCDF file where several temperature 
profiles are all placed in a single one-dimensional array.  You need 
think of the data as a set of tuples  (x,y,z,t,temp) all a function of 
an index.  ncBrowse has no way to pull this data back into a set of 
individual profiles.

	I've played with your included file, but the only sensible plot I 
could make was using the "Map Var..." option and making a plot of xax 
vs. yax.

	My suggestion is to try and find the OPeNDAP server and directly use 
ncBrowse with that.  However, a quick look around and I wasn't able to 
figure out where LAS was getting its data from.

Good luck,

Don
