[netCDF #VHI-280278]: Two simple questions on NetCDF

Hello Nicolás,

I'm afraid I don't have any experience using NASA Panoply so I can't say for 
certain.  It is possible to use netCDF data to define lat/lon boxes, but my 
guess is that these lat/lon coordinates correspond to a point on the map.  The 
method by which this is drawn by the software will depend on the software 
itself.  It sounds like you haven't had any luck with the Panoply 
documentation; have you tried contacting Panoply support?  I'm sorry I can't 
provide a better answer for this.  Other software which may be used to 
visualize netCDF data is listed here:

* http://www.unidata.ucar.edu/software/netcdf/software.html

The netCDF library does not provide a way to consolidate files in the way that 
you describe.  However, the NetCDF Operators package (NCO), maintained by 
Charlie Zender and available here:

* http://nco.sourceforge.net/

offers a number of ways to manipulate files.  Using NCO, it should be possible 
to consolidate individual netCDF files.  In terms of doing this in application 
space via Panoply, I'm afraid I can't say and must refer you, once again, to 
the Panoply maintainers/support folk.

I'm very sorry I can't provide a more immediate solution, but hopefully this 
will help you get started.
