This dataset provides output from a 10-member ensemble global atmosphere reference simulation covering the period 1980 to 2023 produced with the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), using a Tco399 L137 configuration of the IFS, which has an average horizontal grid spacings of ∼28 km. The simulation is constrained by time-evolving external climate forcings, including observed greenhouse gas and aerosol concentrations, and high-resolution satellite-based estimates of daily mean sea surface temperature and daily mean sea ice concentration from ESA CCI version 3.0.1 (https://doi.org/10.1038/s41597-024-03147-w). The atmosphere model is based on IFS Cycle 48R1, with some modifications for consistency with the Phase 1 Destination Earth Climate Adaptation Twin (climateDT), and is coupled to the ecLand land-surface and ecWAM ocean wave models. These data were produced as part of the Horizon Europe project European Eddy-Rich Earth System Models (EERIE, https://eerie-project.eu/). This dataset contains 6-hourly instantaneous and 6-hourly accumulated fluxes, and daily means. Pressure level output is provided on 19 pressure levels. The stream "clte" contains 6-hourly and daily mean variables. See below for example MARS requests, and consult the Parameter Database (https://codes.ecmwf.int/grib/param-db/) for information on the GRIB2 param IDs. Individual ensemble members are retrieved through the "realization" key, currently this has to happen one-by-one. For an extended description of the dataset consult the data description paper (https://doi.org/XXXXXX). For questions contact matthias.aengenheyster@ecmwf.int or christopher.roberts@ecmwf.int
