You will find one CDS catalogue entry called "CORDEX regional climate model data on single levels for Europe". Please note that not all the combinations of selections exist. This feature is inherited from the ESGF system, where the main target is to publish as much as possible data and even publish incomplete datasets, which might be of use. This allows to have more data available with the price that not everything is fully complete. Below we describe briefly all widgets available at the CDS catalogue download tab. See See the CDS form at https://cds.climate.copernicus.eu/cdsapp#!/dataset/projections-cordex-single-levels?tab=form More details are given at CORDEX: Regional climate projections
01. Experiment
Select the experiment of your interest. Evaluation is an experiment for a past period using reanalysis (ERA-Interim boundary conditions). Historical experiments are also for the past, but using Global Climate Models (GCM) as boundary conditions. Three scenarios for the future can be selected: RCP 2.6, RCP 4.5 and RCP 8.5 representing different pathways of the future climate forcing.
...
Select the temporal resolution of your choice.
03. Variable
Select the parameter(s) you are interested in. Since no separate pressure level catalogue entry exists in the CDS here you can find some data on some of the main pressure levels.
...
Select the simulation version. Mostly we have only one simulation per model, therefore usually the previous choices leave only one choice. . The different versions are available for the HIRHAM5, RACMO22E and RCA4 models.
07. Ensemble member
Select the ensemble members of the experiment. The ensemble members are coming from the driving Global Climate Models (GCMs).
