Observations to Improve Climate Models
The 2012–2021 Strategic Plan emphasizes the need for synergy between Earth observations and Earth system modeling—two cor- nerstones of
Obs4MIPs currently focuses on an important, achievable, and otherwise unaddressed objective: providing researchers with the observational data most needed for evaluating climate models, in a format that enables direct comparisons with CMIP model output. Specifically, each Obs4MIPs dataset is formatted according to the latest CMIP requirements and corresponds to a model output field in one or more CMIP experiments. This technical alignment of observational products with model output makes it possible to more effectively compare, evaluate, and ultimately improve climate models. With contributions from NOAA, the European Space Agency, and other new partners, along with guidance from the WCRP Data Advisory Council, Obs4MIPs is growing into a larger, more international enterprise. Efforts are now underway to coordinate the advancement of Obs4MIPs with the next phase of CMIP.
