| - | ===== Overview ===== | ||
| - | |||
| - | |||
| - | The following table summarizes the experiments proposed by PMIP for CMIP6. These | ||
| - | experiments all build from the DECK experiments and are part of the core of PMIP simulations | ||
| - | (~10), which will themselves constitute a basis for other PMIP experiments (sensitivity analyses, | ||
| - | transient simulations starting from the core ones). Within PMIP, each PMIP working group will | ||
| - | organize their set of simulations, as PMIP also federates focused MIPs such as PlioMIP on the | ||
| - | Pliocene climate, LIGMIP on the Last Interglacial, PAST2K on the last two millennia. **For all these periods the model to be used is the same as the one used for future climate | ||
| - | projections.** Therefore depending on the groups the model will be only atmosphere-ocean | ||
| - | coupled models or Earth System models. The reference for the analyses will be the CMIP6 preindustrial | ||
| - | simulation. | ||
| - | |||
| - | Table: summary of proposed experiments. In yellow: PMIP3/CMIP5 experiments. In green: new | ||
| - | experiments for CMIP6. The PMIP3/CMIP5 experiment names in the ESFG nomenclature are indicated in | ||
| - | italic below each period name. | ||

| - | |||
| - | The next phase of PMIP will make use of the PMIP3 boundary conditions whenever possible. A | ||
| - | major foreseen evolution is related to the interactive computation of the dust cycle in | ||
| - | atmospheric models, for which changes in vegetation also have to be taken into account. PMIP2 | ||
| - | and PMIP3 recommended the use of either interactive vegetation or prescribed pre-industrial | ||
| - | vegetation. For PMIP4, those models which include an interactive representation of the dust | ||
| - | cycle will have to account for changes in vegetation. **We invite the modelling groups to indicate their intentions and opinion about this particular topic in the discussion section at the bottom of this page**. | ||
| - | |||
| - | ===== Prioritization ===== | ||
| - | |||
| - | |||
| - | Each proposed PMIP experiment for CMIP6 can be run independently, because they focus on | ||
| - | different time periods. The midHolocene and lgm experiments have been the focus of PMIP | ||
| - | since its start and allow for an evaluation of new model versions since the first atmosphere-only | ||
| - | GCMs in PMIP1. We therefore require one of these two simulations to be performed as an entry | ||
| - | card to CMIP6-PMIP4 experiments. All five PMIP experiments proposed for CMIP6 have equal | ||
| - | priority, each experiment being the core of a set of sensitivity experiments to be run within | ||
| - | PMIP. The organization of the PMIP experiments w.r.t CMIP6 is given in the figure below. | ||
