Title

We recommend to use following formula:

<MODEL ACRONYM> <PROJECT> <OFFICIAL EXPERIMENT ACRONYM> (<experiment number in Taylor document>) r<realisation number>[<realisation letter>] <output type>

Examples:

  • NorESM1-M CMIP5 historicalExt (3.2) r1 raw output

  • NorESM1-ME CMIP5 rcp85 (4.2) r1a raw output

  • NorESM1-ME CMIP5 rcp85 (4.2) r1 cmor-processed output

<output type> should be a brief and general description of the type of output, e.g. raw output or cmor-processed output. Information on data format etc will be specified elsewhere.

<realisation letter> can be used if an experiment is composed of several cases – e.g., NorESM1-ME CMIP5 rcp85 r1 is associated with the cases NRCP85AERCNOC_f19_g16_01 and NRCP85AERCNOC_f19_g16_02 – and one intends to create a dataset for each cases.

For CMIP5 output, specify Integrated Earth System Approach to Explore Natural Variability and Climate Sensitivity (EarthClim)

Conforms to

If in doubt, specify “Climate and Forecast (CF) metadata conventions”

Provenance

In case the output has been compressed, specify “gzip compression of restart files and conversion of history output to compressed NetCDF-4 format” and state the time stamp of the last compressed restart file.

Please add additional provenance entries in case further manipulations have been performed on the output.
