An independent implementation, also developed and maintained by Unidata, is written in 100% Java, which extends the core data model and adds additional functionality. The core library is written in C, and provides an API for C, C++ and two APIs for Fortran applications, one for Fortran 77, and one for Fortran 90.

The software libraries supplied by UCAR provide read-write access to netCDF files, encoding and decoding the necessary arrays and metadata. NetCDF users can create HDF5 files with benefits not available with the netCDF format, such as much larger files and multiple unlimited dimensions.įull backward compatibility in accessing old netCDF files and using previous versions of the C and Fortran APIs is supported.

Starting with version 4.0, the netCDF API allows the use of the HDF5 data format. The data are stored in a fashion that allows efficient subsetting. The format is platform independent, with issues such as endianness being addressed in the software libraries. This means that there is a header which describes the layout of the rest of the file, in particular the data arrays, as well as arbitrary file metadata in the form of name/value attributes.

The CDF5 format is supported, in coordination with the parallel-netcdf project.Īll formats are " self-describing".

The HDF4 SD format is supported for read-only access.

The netCDF-4/HDF5 format was introduced in version 4.0 it is the HDF5 data format, with some restrictions.

The 64-bit offset format was introduced in version 3.6.0, and it supports larger variable and file sizes.

The classic format was used in the first netCDF release, and is still the default format for file creation.

The netCDF libraries support multiple different binary formats for netCDF files: The format was originally based on the conceptual model of the Common Data Format developed by NASA, but has since diverged and is not compatible with it.

7 Interoperability of C/Fortran/C++ libraries with other formats.

Further releases are planned to improve performance, add features, and fix bugs.

Version 4.7.0 (2019) added support for reading Amazon S3 objects.

Version 4.3.0 (2012) added a CMake build system for Windows builds. Version 4.1 (2010) added support for C and Fortran client access to specified subsets of remote data via OPeNDAP. Version 4.0 (released in 2008) allowed the use of the HDF5 data file format. The original netCDF binary format (released in 1990, now known as "netCDF classic format") is still widely used across the world and continues to be fully supported in all netCDF releases. The project started in 1988 and is still actively supported by UCAR. NetCDF Classic and 64-bit Offset Format are an international standard of the Open Geospatial Consortium. They are also the chief source of netCDF software, standards development, updates, etc. The project homepage is hosted by the Unidata program at the University Corporation for Atmospheric Research (UCAR). NetCDF ( Network Common Data Form) is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data.
