For transient-deglaciation-prescribed-glac1d-methane (r1i1p1f1):
The transient experiment was 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), Kleinen et al. (2021) and Kleinen et al. (2022).
For the experiment, the model was integrated from a glacial state at 23 ka to the year 1950 with prescribed atmospheric greenhouse gas concentrations (Köhler et al., 2017) and insolation (Berger & Loutre, 1991). Ice sheets and surface topographies were prescribed from GLAC-1D (Tarasov et al., 2012) reconstructions. All forcing fields are updated every 10 years of the simulations and initiate changes in the topography, glacier mask, river pathways, ocean bathymetry, and land-sea mask.
For transient-deglaciation-prescribed-glac1d-methane (r1i1p1f2):
This experiment is derived from the r1i1p1f1 experiment. It is branched off at 18 ka BP, and starting at 15.2 ka BP, meltwater from the Laurentide ice sheet was removed from the system and stored. The accumulated meltwater was released over a period of 1200 years starting at 12.8 ka BP. This induced a collapse of the AMOC, leading to climatic conditions very similar to the Younger Dryas cold period seen in climate reconstructions. After the end of the meltwater release, the circulation recovered quickly and climatic conditions converged with the r1i1p1f1 experiment.
Important:
Please be aware that due to CMORization constraints data set time values concerning to "Before Present(BP)" time got a year offset (+25001). Means for example year range 2001 to 25000 model time is equal to 23000 to 1 BP.
