The CMIP6 data archive is distributed through the ESGF. 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). Dedicated ESGF data nodes are used for C3S in France (at IPSL) and in Germany (DKRZ), respectively. Similarly, the decadal climate prediction project (DCPP) data in the Climate Data Store (CDS) are a targeted, quality-controlled subset of the DCPP commissioned by C3S. The published datasets are the ones which took part on the C3S sectoral demonstrator service (see details at https://climate.copernicus.eu/sectoral-applications-decadal-predictions)

INSTEAD, NEW TABLE PROPOSED
| CDS parameter name | ESGF variable id | units | Standard name (CF) | Long name | Description |
|---|---|---|---|---|---|
| 500 hPa geopotential height | zg500 | m | geopotential_height | Geopotential Height at 500hPa | Gravitational potential energy per unit mass normalised by the standard gravity at 500hPa at the same latitude. |
| Daily maximum near-surface air temperature | tasmax | K | air_temperature | Daily Maximum Near-Surface Air Temperature | Daily maximum temperature of air at 2m above the surface of land, sea or inland waters. |
| Daily minimum near-surface air temperature | tasmin | K | air_temperature | Daily Minimum Near-Surface Air Temperature | Daily minimum temperature of air at 2m above the surface of land, sea or inland waters. |
| Near-surface air temperature | tas | K | air_temperature | Near-Surface Air Temperature | Temperature of air at 2m above the surface of land, sea or inland waters. 2m temperature is calculated by interpolating between the lowest model level and the Earth's surface, taking account of the atmospheric conditions. |
| Precipitation | pr | kg m-2 s-1 | precipitation_flux | Precipitation | The sum of liquid and frozen water, comprising rain and snow, that falls to the Earth's surface. It is the sum of large-scale precipitation and convective precipitation. This parameter does not include fog, dew or the precipitation that evaporates in the atmosphere before it lands at the surface of the Earth. This variable represents amount of water per unit area and time. |
| Sea level pressure | psl | Pa | air_pressure_at_sea_level | Sea Level Pressure | The pressure (force per unit area) of the atmosphere at the surface of the Earth, adjusted to the height of sea level. It is a measure of the weight that all the air in a column vertically above a point on the Earth's surface would have, if the point were located at sea level. It is calculated over all surfaces - land, sea and inland water. |
Grids
DCPP data like the rest of CMIP6 is reported either on the model’s native grid or re-gridded to one or more target grids with data variables generally provided near the centre of each grid cell (rather than at the boundaries). A grid_label (found in the file name following the ensemble identifier and also in the file's global metadata attributes) indicates whether the data is provided on the model's native grid (gn) or has been re-gridded (gr) to a target grid. For DCPP data in the CDS, only data from the EC-Earth3 model has been re-gridded to a target grid, data from the other models are provided on each model's native grid. The file's "nominal_resolution" global metadata attribute gives an indication of the resolution of the data, for the DCPP data in the CDS the nominal resolution of the models is 100km (except for the MPI-ESM1-2-LR model, which is 250 km).
