Lessons learned from 25 years of PMIP model-data distribution

Abstract

Climate models are improved iteratively, as scientific knowledge, along with computing and storage technology progress. Sharing and comparing models and their output to paleo reconstructions is an essential part of this process. This can be done by sharing data directly between individuals, but is more efficient when formally organized as a MIP (Model Intercomparison Project), where all contributors and users adopt the same standards. The Paleoclimate Modelling Intercomparison Project (PMIP), started in 1990 (Joussaume and Taylor 1995), was one of the early MIPs, following the AMIP example (Gates et al. 1998).
