Abstract	Project: CMIP7 CMIP core common experiments i.e. the DECK (Diagnostic, Evaluation and Characterization of Klima). Produced by: CNRM (Centre National de Recherches Meteorologiques, Toulouse 31057, France), CERFACS (Centre Europeen de Recherche et de Formation Avancee en Calcul Scientifique, Toulouse 31057, France) (Using Model/Source: CNRM-ESM2-1e with Experiment historical) CNRM-ESM2-1e is the CNRM Earth System model version 2 designed for CMIP6 on the basis of the physical core CNRM-CM6-1 (Voldoire et al. 2019). In concentration mode, it is the same model as CNRM-ESM2-1 (Séférian et al. 2019), it only differs from CNRM-ESM2-1 in emission-driven mode (see Bossert et al. 2026). The main adaptations consist in a better conservation of the carbon in all the components leading to a more consistent/realistic carbon flux evolution in historical simulations. Experiment: Simulation of the climate of the recent past (typically meaning 1850 to present-day) with prescribed carbon dioxide concentrations (for prescribed carbon dioxide emissions, see `esm-hist`). CMIP7 is a project of the World Climate Research Programme (WCRP), providing climate projections to understand past, present, and future climate changes. It is part of the WCRP Earth System Modelling and Observations (ESMO) Core Project, which was formed to coordinate all modelling, data, and observation activities across WCRP and its key partners. Further details can be found here and in the CMIP7 Guidance pages. Parties using CMIP data should ensure they have read the WCRP CMIP (2026) CMIP Data Disclaimer.
