We have had a student finishing a generic browser for netCDF data written as
an IDL program.  I will be announcing it to the netcdfgroup mailing list
soon.  NetCDF permits you to use other tools for browsing the data as
well. The ncdump tool lets you look at it in ASCII form.

NetCDF is not a database system, and in particular does not provide features
in the interface for indexing data by value.  However if you don't need the
facilities of a real database system but do need an interface for accessing
portable scientific data, netCDF may be appropriate. If you have Mosaic or
another WWW browser, I recommend that you look at the netCDF information
we've assembled in the netCDF home page at

        http://www.unidata.ucar.edu/packages/netcdf/

There is information there that is not in the manual, such as who else is
using netCDF, what kinds of things it is used for, and what software is
available for manipulating or displaying netCDF data.
