1.5 Experiments: last glacial maximum (lgm)

Record Label : lgm

Record Title : last glacial maximum

Record identifier : f16f0242-dd9e-11e6-b89b-ac72891c3257

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.
