Because good research needs good data

CF (Climate and Forecast) Metadata Conventions

Extensions

COARDS Conventions

Developed by the Cooperative Ocean-Atmosphere Research Data Service (COARDS), these conventions constitute a standard set of metadata to include in netCDF files, allowing them to be shared and interchanged.

The COARDS Conventions are generalised and extended by the CF (Climate and Forecast) Metadata Conventions.

Tools

CF Compliance Checker

A utility that checks netCDF files for CF-compliance.

CMOR - Climate Model Output Rewriter

A set of C-based functions, with bindings to both Python and FORTRAN 90, that can be used to produce CF-compliant netCDF files.

NetCDF

A set of software libraries and self-describing, machine-independent data formats that conform to the CF metadata conventions. They support the creation, access, and sharing of array-oriented scientific data.

Use Cases

BADC - British Atmospheric Data Centre

The Natural Environment Research Council's (NERC) Designated Data Centre for the Atmospheric Sciences. It uses the CF-Compliant NetCDF format for its datasets.

BODC - British Oceanographic Data Centre Published Data Library

This national facility for looking after and distributing data concerning the marine environment requires that data sets use a well-documented format such as CF-compliant NetCDF and be accompanied by a Dublin Core record as well as discovery metadata in a recognised standard such as DIF or FGDC/CDGM.

Met Office Hadley Centre

A number of projects at the Hadley Center require CF-Compliant NetCDF files, including HadAT and Transpose AMIP.

NCAR - National Center for Atmospheric Research

The NCAR Research Data Archive uses CF-Compliant NetCDF files.

Ocean Networks Canada

Ocean Networks Canada operates the NEPTUNE and VENUS cabled ocean observatories that collect data on physical, chemical, biological, and geological aspects of the ocean over long time periods, supporting research on complex Earth processes. The CF standard is used within netCDF data products delivered through the Oceans 2.0 interface and via OPeNDAP webservices.
