When maven resolves the code quoted, this is the library that downloads:
Maven: edu.ucar:netcdf4:4.5.5
Version seems to be 4.5.5 for the netcdf java library. For the netcdf C
libraries, I downloaded and installed: netCDF 4.3.3.1. Specifically, this
file:
http://www.unidata.ucar.edu/downloads/netcdf/ftp/netCDF4.3.3.1-NC4-DAP-64.exe
