Abstract:?The goal of the Paleoclimate Modelling Intercomparison Project (PMIP) is to provide a coordinated framework for the paleoclimate modelling and evaluation, to understand the response of climate system to different climate forcings in the past, and, to constrain the projection of future climate. PMIP also contributes the improvement of climate models by comparing simulations and understanding the model uncertainties. PMIP is now proceeding to the fourth phase (PMIP4) and further enhances the collaboration with CMIP6. Simulations of five different periods have been designed to address the objectives of CMIP6: the millennium prior to the industrial epoch (past1000); the mid-Holocene, the Last Glacial Maximum; the Last Interglacial; and the mid-Pliocene Warm Period. Besides, sensitivity experiments are designed to access the role of different forcing factors. PMIP4 not only provides a large number of simulations for paleoclimate research, but also collaborates with other CMIP6 MIPs by providing necessary variables.
