Network Common Data Form (NetCDF)

Network Common Data Form (NetCDF)

NetCDF NetCDF (Network Common Data Form) is a set of software libraries and machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. It is also a community standard for sharing scientific data. The Unidata Program Center supports and maintains netCDF programming interfaces for C, C++, Java, and Fortran. Programming interfaces are also available for Python, IDL, MATLAB, R, Ruby, and Perl.

Data in netCDF format is:

  • Self-Describing. A netCDF file includes information about the data it contains.
  • Portable. A netCDF file can be accessed by computers with different ways of storing integers, characters, and floating-point numbers.
  • Scalable. Small subsets of large datasets in various formats may be accessed efficiently through netCDF interfaces, even from remote servers.
  • Appendable. Data may be appended to a properly structured netCDF file without copying the dataset or redefining its structure.
  • Sharable. One writer and multiple readers may simultaneously access the same netCDF file.
  • Archivable. Access to all earlier forms of netCDF data will be supported by current and future versions of the software.
