Files with NC filename extension are associated with NetCDF (Network Common Data Form) service. NC files are used for storing collected scientific data and related metadata. NC files can be opened with a popular software MATLAB.

NC files are based on a binary data standard developed in 1997. NC is the evolution of CDF format developed by NASA. NC version 4.0 and later support HDF5 data and more features are planned to be added in the future.
