The Nation’s leading modeling centers met for the 4th time to improve coordination

Representatives from the Nation’s six major climate modeling centers will met for the 4th year in a row to work towards developing a common national climate modeling strategy and coordinate activities at the centers. Through annual discussions drawing upon the centers’ complementary strengths, the U.S. Climate Modeling Summit (USCMS) provides a foundation to improve our nation’s modeling and prediction capabilities. Building on outcomes from the 2017 USCMS, day one of this year’s meeting included a workshop on “Land-Atmosphere Interactions and Extremes”. The workshop focused on prioritizing research and development for the modeling centers and promoting interactions among the centers and with the broader community to advance the workshop topical areas, such as hydrological extremes, and coastal, land and human interactions. Day two involved high-level discussions among modeling center representatives as well as sponsoring agency representatives to improve coordination between the groups. This year the meeting also focused on initial progress made at centers for Phase 6 of the Coupled Model Intercomparison Project. The USCMS is an activity of the USGCRP – Interagency Group for Integrative Modeling (IGIM). For the past year, the NOAA National Weather Service’s Hendrik Tolman has served as USCMS Chair and NOAA Research’s Annarita Mariotti has served as USCMS Coordinator; both have served a leading role on the organizing committee for this meeting. 

The 4th USCMS convened April 4 and 5th at the National Center for Weather and Climate Prediction in College Park.

About MAPP
The Modeling, Analysis, Predictions, and Projections (MAPP) Program is a competitive research program in NOAA Research’s Climate Program Office. MAPP’s mission is to enhance the Nation’s and NOAA’s capability to understand, predict, and project variability and long-term changes in Earth’s system and mitigate human and economic impacts. To achieve its mission, MAPP supports foundational research, transition of research to applications, and engagement across other parts of NOAA, among partner agencies, and with the external research community. MAPP plays a crucial role in enabling national preparedness for extreme events like drought and longer-term climate changes. For more information, please visit
