Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hello once again! I just want to thank everyone who responded to my post earlier. The question concerned Navo's NetCDF convention and how to store longitude and latitude data for an irregular grid. The predefined lat and lon variables were coordinate variables and, as such, 1 dimensional. I needed to store 2 dimensional coordinates. For the moment, we have decided that we will be using the most common suggestion which was to use coordinate variables, such as x(x) and y(y), as indices into longitude(x, y) and latitude(x, y) variables. This will suffice and work quite well for our purposes. That decision may change in the coming month however since I have learned that there are some predefined grid variables, grid_lon and grid_lat, that may be of use. These new variables are not well described and I haven't heard from Navo about them yet. Once again, thank you to everyone who offered suggestions and help. Matthew Hanna
