Dear Ethan, Don, others, > Yes, the netCDF-Java Grid API is the obvious place to put this > capability.

I would like to contribute if I can, although I don't have any experience coding with the NetCDF-Java interface so far. I would be in favour of a generic solution, but I'm wondering if, in this case, it isn't something that should go into IDV itself. The fact that a grid wraps and how to deal with it is something application-domain specific. NetCDF (theoretically) doesn't have to contain earth grids. There are other applications where the functionality would make sense (direction axes), so it could be seen as a generic dimension property (solve in NetCDF) or as something earth-grid specific (solve in IDV). If it's solved in NetCDF, shouldn't it be solved in the base C library as well? Ferret (noaa) has a similar problem, and solves it in the application with a "modulo" flag for dimensions and recognition of specific lon dimensions. I'm not sure if they split requests in 2 when requesting a small region, but I can find out if there's an interest.
