CF-Convention Compliance Checker for NetCDF Format

This form allows you to run the 'cfchecks.py' script to check that the contents of a NetCDF file comply with the Climate and Forecasts (CF) Metadata Convention. The CF-checker was originally developed at the Hadley Centre for Climate Prediction and Research, UK Met Office by Rosalyn Hatcher. This work was supported by PRISM (PRogramme for Integrated Earth System Modelling).

Development and maintenance for the CF-checker has now been taken over by the NCAS Computational Modelling Services (NCAS-CMS).

To check your file, please use the drop down menu to select the version of the CF conventions to check against, enter the file name in the box below then press Check file. You can use the Browse... button to help you select the file.

For details of the NetCDF format and the CF Convention go to the NetCDF format page or the CF Convention page.

There are some requirements of the convention that it is difficult or impossible to implement in the Checker. A list of aspects which the checker does not check can be found here.

Please email rosalyn.hatcher AT ncas.ac.uk or raise an issue on github if you encounter any problems.
