PMIP4 mid-holocene run

Impose Mid-Holocene (6 kyr ago) boundary conditions for orbital parameters and the atmospheric concentration of well-mixed greenhouse gases. 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. (CMIP6 Experiment).

Users can access the data from the Earth System Grid Federation or Climate Data Gateway as registered users; see the 'Related links' section.

Diagnostic plots are also available from the 'Related links'.

NCAR users may access the data from Glade; path(s) listed in the 'Additional Information' section.
