PalMod2 MPI-M MPI-ESM1-2-CR-CH4 future-methane

Project: PalMod2 - From the last interglacial to the anthropocene - modeling a complete glacial cycle. The PalMod project (https://www.palmod.de/) aims for a better understanding of how slow feedbacks in the Earth system operate. Using the new insights into Earth system dynamics, PalMod will also make projections of the future climate over the next few millennia. The project PalMod is in the second phase. Summary: These set of future climate scenario experiments were performed with the Max Planck Institute for Meteorology Earth System Model version 1.2 in coarse resolution (MPI-ESM-CR). The model includes the spectral atmospheric model ECHAM6.3 at T31 horizontal resolution (approx. 3.75°) and 31 vertical levels, the land surface vegetation model JSBACH3.2, and the primitive equation ocean model MPIOM1.6 with a nominal resolution of 3°. The model has been extended with a full methane cycle, including a simplified atmospheric chemistry, as described in Kleinen et al. (2020) and Kleinen et al. (2021). The model was integrated from a preindustrial state to 3050CE following the SSP scenarios SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 with CO2 and N2O following Meinshausen et al.(2020) until 2500, followed by an extension until 3050CE we obtained using the CLIMBER2 model, as described in Kleinen et al. (2021).
