What is a CDF file?

File create in the Common Data Format (CDF), a format used for storing scalar and multidimensional data in a manner independent of the target platform and discipline; used as a scientific data storage and interchange format by various researchers and organizations and often by those in government.

More Information

Common Data Format files can be manipulated using the CDF software toolkit provided by the Space Physics Data Facility (SPDF), a part of the Goddard Space Flight Center (GSFC). The software is cross-platform.

The Common Data Format is supported with interfaces to programming languages such as C, Fortran, C#, Perl, Java. It is also supported by commercial software packages such as MathWorks MATLAB, ITT Visual Information Solutions' Interactive Display Language (IDL), and Weisang FlexPro.

The CDF format has been adopted as a standard format by organizations such as the International Solar-Terrestrial Physics (ISTP) project and the Central Data Handling Facilities (CDHF) project, a scientific data processing entity.

NOTE: The CDF format differs from the NetCDF format, which is based on CDF but uses slightly different conventions. Sometimes NetCDF files use the ".cdf" extension, but the format is incompatible.
