Ghansham, If I understand your first query correctly, you have data from three sources that perhaps nearly, but don't quite, line up in space and time. It is certainly possible to assign dimenions lat1, lon1, lat2, lon2, lat3, lon3 in netCDF to describe the datasets. Alternatively, if you are using netcdf4, you can use the same names (lat and lon) for dimensions in three different groups. I'm not sure what you mean when you say that netcdf-java only picks up one of the datasets. The best answer on how to package your data is to suggest looking at it from the perspective of the end user or application, as ultimately, this is what matters most. For instance, you could fudge the three dataset grids into an average and report only one lat/lon grid, or you could trust the end user to interpret the three grids appropriately. As to your second query, can you clarify what you need or are trying to do?
