Annual U.S. Climate Modeling Summit

To improve the coordination and communication of national climate modeling goals and objectives, USGCRP's Interagency Group on Integrative Modeling (IGIM) is convening an annual U.S. Climate Modeling Summit beginning in 2015. The Summit brings together representatives from the U.S. “CMIP-class” climate model development centers and from operational climate prediction programs. Specifically, two representatives—one lead and one additional delegate—from each of the following groups are invited to participate in the Summit: Geophysical Fluid Dynamics Laboratory (GFDL CM/ESM); Climate Forecast System (CFS); Goddard Institute for Space Studies (GIS Model E); Goddard Earth Observing System (GEOS-5); Community Earth System Model (CESM); and Accelerated Climate Model for Energy (ACME).

As envisioned by the IGIM, the high-level Summit objectives include:

  • Developing a shared understanding of modeling groups’ directions and implementation strategies,
  • Identifying opportunities for enhanced coordination and synergy among modeling groups, and
  • Identifying outreach opportunities to user communities

Fourth Meeting

The fourth US Climate Modeling Summit (USCMS) will include a Land-Atmosphere Interactions and Extremes Workshop on April 4, 2018. Land surface processes are increasingly being recognized as an important source of predictability at weather to climate time scales, and the land surface represents an important intersection between human activities and the Earth system. The workshop will provide a forum for discussions to prioritize research and development for the modeling centers and to promote interactions among the centers and between the centers and the broader community to advance the workshop topical areas. This workshop will consist of 4 parts. Part I will provide an overview of the state-of–the-art of land modeling at the six centers. Parts II through IV will consist of Subject Matter Experts presenting papers and a subsequent group discussion. The subjects addressed will be land-atmosphere interactions and extremes (Part II), hydrological extremes (Part III) and Coastal, land and human interactions (Part IV). 
 
On April 5th, 2018, the USCMS members will meet to exchange of information between modeling centers and improve coordination among centers and sponsoring IGIM agencies. The first part of the meeting will include updates from IGIM, the USCMS Chair and the centers, with a particular focus on updates and activities during the past year. There will also be a discussion on outcomes from the Land-Atmosphere Interactions and Extremes Workshop.The second part of the meeting will be dedicated to the initial progress made at centers for CMIP6.

Third Meeting

The third annual meeting will be held March 15, 2017, in the Washington, DC area following an Arctic workshop convened by the CMS participants. The US CMS meeting works on building synergies in themes very relevant to multiple US agencies for their Earth system modeling and prediction efforts. This year's themes include: 1) Arctic science and predictions conducted/planned at the various modeling centers; 2) Subseasonal-to-seasonal predictability that strives for seamless prediction capabilities; 3) Model Intercomparison Projects that include discussion/action on the CMIP6 activities; 4) Next generation HPC requirements for weather/climate.

Second Meeting

The second meeting will be held in March 2016 in the Washington, DC area. This meeting is dedicated to more specific exchanges among Centers with the goal of facilitating enhanced coordination on specific items of interest to multiple Centers: 1) CMIP or other Coordinated Modeling activities; and 2) Opportunities and challenges for modeling with high resolution and advanced physical representation. This will be done in the context of USGCRP priorities, and the evolving condition of Federal Supercomputing and Software, and the interfaces with Integrated Assessment and Impact-Adaptation and Vulnerability research.

First Meeting

The first meeting was held in February 2015 in the Washington, DC area. The overarching goal of the meeting was to enhance coordination toward a common national climate modeling strategy and communication with the broader modeling community. The meeting also began to identify priorities for future Summit activities and needs for topical Climate Forums, as recommended by the National Research Council report, A National Strategy for Advancing Climate Modeling.  An initial Climate Forum planned by the Summit leads was held in conjunction with the meeting and focused on U.S. participation in CMIP6.

IA-IAV-ESM Workshop: Toward Multi-Model Frameworks Addressing Multi-Sector Dynamics, Risks, and Resiliency

A Workshop sponsored by the U.S. Department of Energy for the U.S. Global Change Research Program’s Interagency Group on Integrative Modeling and Interagency Coordinating Group: May 24-26, 2016

This workshop is one of several efforts convened under the auspices of the U.S. Global Change Research Program that are 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. The workshop is being coordinated by an Interagency Coordinating Group with technical inputs from a Scientific Steering Group. The agencies that comprise the workshop’s Interagency Coordinating Group share a common interest in the scientific challenges associated with modeling the interactions of human and environmental systems to support risk management.

The workshop addresses the following challenges:

  • Systematize needs and uses: Explore uses, scale and information dependencies associated with these uses, and specific information needs for categories of problems. Discussions at the workshop are intended to help development of a “use typology” that will identify needs to guide research and development of the framework
  • Inventory and evaluate the state of science: Inventory extant and emerging models and frameworks for representing and integrating key processes and interactions. This will include evaluating sector-specific IAV models (ranging from those focused on resource productivity to market interactions), IAMs, a range of approaches for characterizing changes in climate and related physical systems (e.g., hydrology, land cover), and methods for modeling socioeconomic systems and behavior. The workshop will explore data requirements, coupling strategies, mechanisms to capture impact and adaptation information that is not amenable to modeling, approaches for evaluating risk, and model evaluation
  • Develop the conceptual framework: Discuss a conceptual framework for research and modeling that defines data and coupling needs by identifying interactions across scales, sectors, and temporal processes essential for addressing the problems and information needs. Participants will also explore the near-term mechanisms and activities for implementation of the framework concept in ongoing and planned model development activities across the USGCRP and interested research community
  • Identify research needs/opportunities and options for program development: Explore needed advances in fundamental research on Earth systems, environmental, and societal processes; specialized sector-specific models; and models able to represent interactions and tradeoffs across sectors, systems, and time/spatial scales that can contribute to advancing the state of science. This will include identifying research gaps and priorities for different intended applications and user communities
