The Eighth Annual US Climate Modeling Summit (USCMS) workshop and meeting were held on Aug 2-4, 2022 in a hybrid format. This annual event of the Interagency Group on Integrative Modeling (IGIM) under the USGCRP brings together the Nation’s major experimental and operational climate modeling programs to improve coordination and communication of national climate modeling goals and objectives. Co-organized by Ruby Leung of Pacific Northwest National Laboratory and Gokhan Danabasoglu of National Center for Atmospheric Research, the summit workshop and meeting were held at the College Park Marriott Hotel & Conference Center, MD, and through Webex, with logistical support provided by Angela Jefferson and Cheryll Nunez of Lawrence Livermore National Laboratory.
This year, the US modeling centers selected water cycle and water security as the theme of the USCMS workshop. This workshop theme is motivated by the important role water plays in sustaining life and supporting human activities and the need for the Nation to prepare for future challenges in water security to harness the productive power of water and reduce its destructive impacts. Climate models exhibit noticeable biases in simulating different aspects of the water cycle, undermining their ability in meeting the increasing demands for projections of water cycle changes and modeling water security challenges facing the Nation.
