Hello NicolÃs, 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. -Ward > Dear Unidata support, > > My name is NicolÃs Rojas I am an economist from Chile and I am working > on a research project on a highly debated subject on school attendance > in our country. > > For this purpose, I am learning to manipulate a NetCDF rainfall data > set that I found on the web.
