Fifth National Climate Assessment - Read the Report

Interagency Group on Integrative Modeling

USGCRP’s Interagency Group on Integrative Modeling (IGIM) coordinates global change-related modeling activities across the federal government and provides guidance to USGCRP on modeling priorities, including uncertainty quantification and data requirements. IGIM’s scope encompasses the atmospheric, oceanic, cryospheric, and terrestrial domains; human systems are treated as an integral component of each domain.

Annual U.S. Climate Modeling Summit

To improve the coordination and communication of national climate modeling goals and objectives, IGIM convenes an annual U.S. Climate Modeling Summit, beginning in 2015. The Summit brings together representatives from the U.S. Coupled Model Intercomparison Project (CMIP)-class climate model development centers and from operational climate prediction programs.

Multi-sector and Integrated Assessment Modeling

IA-IAV-ESM Workshop: Toward Multi-Model Frameworks Addressing Multi-Sector Dynamics, Risk, and Resiliency is one of several efforts intended to develop concepts for a modeling framework or architecture to couple Impacts, Adaptation and Vulnerability (IAV) models; Integrated Assessment (IA) models; and climate, Earth system, hydrology, land use, demography, and other models. The framework will facilitate integration of a wide range of model capabilities to meet a growing societal need to better understand the potential for cascading impacts of interacting societal and environmental change across sectors and scales.

Other Activities

  • IGIM has held joint meetings with the Interagency Observations Working Group (ObsIWG) on potential collaborations surrounding Climate Observing Systems Simulation Experiments (C-OSSEs) and on Climate Process Testbeds

  • To help address challenges in improving model resolution, DOE and NOAA jointly hosted a workshop on High-Resolution Coupling and Initialization to Improve Predictability and Predictions in Climate Models, September 30–October 2, 2015, with over 40 participants from both the prediction and projection communities. Participants summarized the current state of research surrounding high-resolution climate modeling, identified common challenges across communities, and proposed a collaborative research framework for quantifying the benefits of high-resolution coupled modeling for reducing model biases and for improving prediction skill on sub-seasonal to seasonal scales

  • Jointly-funded proposals in response to solicitations:

    • National Multi-Model Ensemble (NOAA, DOE, Office of Naval Research, NASA)

    • Decadal and Regional Climate Prediction using Earth System Models (EaSM) (NSF-USDA-DOE)

    • NASA Research Opportunities in Earth and Space Sciences (ROSES) (NASA, DOE, USDA)
