The CMIP6 data archive is distributed through the ESGF though many national centres have either a full or partial copy of the data. A quality-controlled subset of CMIP6 global climate projection data are made available through the Climate Data Store (CDS) for the users of the Copernicus Climate Change Service (C3S). Likewise, tThe decadal climate prediction project (DCPP) data in the Climate Data Store (CDS) are a targeted, quality-controlled subset of the wider DCPP datacommissioned by C3S.

Decadal Climate Prediction Project Data in the CDS

...

Data for the dcppA-hindcast and dcppB-forecast experiments published in the CDS are generated from simulations run by the models described in the table below. The model descriptions presented here are harvested from the dataset DOIs DOI pages held at the World Data Centre for Climate (WDCC), further model details can be found on the ES-DOC. The EC-Earth3, MPI-ESM1-2-HR and HadGEM3-GC31-MM models were configured with 360-day years (where every month has 30 days), whereas the CMCC-CM2-SR5 model was configured with a 365 day year (with an irregular number of days in each month).

Description

EC-Earth3

EC Earth Consortium

The model used in climate research named EC Earth 3.3, released in 2019, includes the components:

  • atmos: IFS cy36r4 (TL255, linearly reduced Gaussian grid equivalent to 512 x 256 longitude/latitude; 91 levels; top level 0.01 hPa),
  • land: HTESSEL (land surface scheme built in IFS),
  • ocean: NEMO3.6 (ORCA1 tripolar primarily 1 deg with meridional refinement down to 1/3 degree in the tropics; 362 x 292 longitude/latitude; 75 levels; top grid cell 0-1 m),
  • seaIce: LIM3.

The model was run in native nominal resolutions: atmos: 100 km, land: 100 km, ocean: 100 km, seaIce: 100 km.

XX FOR THE TIME BEING THIS DATA IS NOT YET AVAILABLE, SO WE WILL REMOVE THIS ROW IF THIS WILL BE THE CASE. HOWEVER, I AM WONDERING IF THERE IS ALREADY ANY DESCRIPTION OF THE MODEL EXISTS TO ANTICIPATE THE CONTENT HERE.

The DCPP experiments published in the CDS, are a suite of overlapping simulations that are initialised every year throughout the duration of the start-date range specified by the experiment. The exact start-dates simulations begin in the November of the year preceding the forecast period to allow for DJF (December, January, February) seasonal averages to be calculated. There are 10 simulations for each start-date.
