endy: as long as possible to have >= 100 stabilised years (I.e 500 to 1000 years for the simulation)
description: Impose Last Glacial Maximum (21 kyr ago) boundary conditions for ice-sheet and land-sea mask, the atmospheric concentration of well-mixed greenhouse gases and orbital parameters. Run for at least 100 years after spin-up. It is mandatory that the model versions used for the PMIP-CMIP6 experiments are the exactly the same as for the other CMIP6 experiments, in particular the DECK and historical simulations.
comment: main forcings : ice-sheet; trace gases, orbital parameters dust (forcing, or feedback if dust cycle represented in model)
