Abstract
Abstract. With version 2.51 of the ECHAM/MESSy Atmospheric Chemistry (EMAC) model three types of reference simulations as recommended by the Chemistry-Climate Model Initiative (CCMI) have been performed: hindcast simulations (1950–2011), hindcast simulations with specified dynamics (1978–2013), i.e., nudged towards ERA-Interim reanalysis data, and combined hindcast and projection simulations (1950–2100). The manuscript summarises the updates of the model system and details the different model setups used, including the on-line calculated diagnostics. Simulations have been performed with two different nudging setups, with and without interactive tropospheric aerosol, and with and without a coupled ocean model. Two different vertical resolutions have been applied. The on-line calculated sources and sinks of reactive species are quantified and a first evaluation of the simulation results from a global perspective is provided as a quality check of the data. The focus is on the inter-comparison of the different model setups. The simulation data will become publicly available via CCMI and the CERA database of the German Climate Computing Centre (DKRZ). This manuscript is intended to serve as an extensive reference for further analyses of the ESCiMo simulations.
