Overview of CCMVal simulations
in support of upcoming ozone and climate assessments

- CCMVal Example Headers and Reformatting Routine -

The output of all model runs will be collected in Climate and Forecast (CF) standard compliant netCDF format for any future CCMVal data requests. CCMVal will use a list of over 150 quantities, many of which have not been in the CF standard name table. The additional names needed for CCMVal have been defined and are now accepted. For the CF standard name table, please see To facilitate model analysis, all modeling groups are asked to provide model output in the agreed format.

This table provides example headers for all CCMVal Fields and a reformatting routine (program that convert an arbitrary netCDF file into a netCDF-file that is CF compliant and ensures that the submitted files follow the CCMVal naming convention). The example headers and reformatting tool below might still slightly change, depending on feedback we receive. Therefore, please visit this website again shortly before you convert your model output to the requested CCMVal naming convention.
  • The purpose of this reformatting tool is to convert an arbitrary netCDF file to a CF1.1 netCDF file, using the name convention of the CCMVal Data Request. Please use the reformatting routine to produce the output for BADC. zip-file avilable here.
  • Please see the CCMVal-2 Data request 2008 for additional information on the output names.
