 The netCDF Java library provides an interface for scientific data access.
 It can be used to read scientific data from a variety of file formats including netCDF, HDF, GRIB, BUFR, and many others.
 By itself, the netCDF-Java library can only write netCDF-3 files.
 It can write netCDF-4 files by using JNI to call the netCDF-C library.
 It also implements Unidata's Common Data Model (CDM) to provide data geolocation capabilities.
