An extension to the netCDF API which provides support for coordinate systems, scale/offset/missing data, and NcML.

- Coordinate systems allow the specification and recognition of general and georeferencing coordinate systems within a netCDF dataset.
- Scale/offset/missing data handles the conversion of integer data to floating point, and the interaction with missing data values
- NcML, the NetCDF Markup Language, is an XML schema for showing, adding and changing netCDF metadata in XML. NcML dataset allows you to create virtual netCDF datasets, including combining multiple netCDF files into one dataset.
