NetCDF Tutorial

This tutorial aims to give a quick and painless introduction to netCDF.

For the basic concepts of netCDF see Intro. Read this to understand the netCDF data models and how to use netCDF.

For sets of examples of increasing complexity see Examples. The example programs are provided for each of four netCDF API languages, C, C++, F77, and F90. (No new netCDF-4 API extensions are used in these examples.)

For a quick reference to the important functions in the netCDF-3 C, C++, Fortran 77, and Fortran 90 APIs, with hyper-links to the full documentation of each function, see Useful Functions.

To learn about the new features of netCDF-4, see API-Extensions. For some examples see NetCDF-4 Examples.

NetCDF interface guides are available for C (see The NetCDF C Interface Guide), C++ (see The NetCDF C++ Interface Guide), Fortran 77 (see The NetCDF Fortran 77 Interface Guide), and Fortran 90 (see The NetCDF Fortran 90 Interface Guide).

This document applies to netCDF version 4.1.3; it was last updated on 10 June 2011.
