This multi-day workshop will bring together researchers, data producers, end users, and interagency representatives to understand the state of the nation’s decision-relevant regional climate projections and carry that understanding forward to enable the development of guidelines for the usage and evaluation of such projections. Numerous approaches will be discussed, including statistical downscaling, dynamical downscaling, hybrid downscaling, and regionally refined global modeling. With these as a foundation, there is much to be learned by sharing knowledge, establishing common ground, and beginning to build a community of practice.
This workshop is coordinated by the U.S. Global Change Research Program (USGCRP) Interagency Group on Integrative Modeling (IGIM) and the Federal Adaptation and Resilience Group (FARG). Participation is anticipated from most major U.S. federal agencies and their partners who are involved in the production and dissemination of regional climate data products, including the US. Department of Energy (DOE), the National Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA), the U.S. Environmental Protection Agency (EPA), and the Department of Defense’s (DoD) Strategic Environmental Research and Development Program and Environmental Security Technology Certification Program (SERDP & ESTCP). Participation is solicited and encouraged from a wide range of scientists and data users of regional climate data products across the U.S.
The primary objective of this workshop is to enable the development of guidelines for production, evaluation, and utilization of high-resolution (<15 km) regional climate projections of impact-relevant variables (e.g., surface air temperature, precipitation, humidity, winds) spanning the historical record and the 21st century. To achieve this goal, the workshop will:
The workshop is by invitation only and there is no registration fee. Attendees represent a diverse range of professionals across the scientific and end-user communities and were nominated by members of the workshop's Interagency Steering Committee.
The workshop will include keynote speeches and interactive breakout sessions. The workshop planning committee will collect topics for breakout sessions from attendees prior to the event. Moderators will be assigned to engage and balance participation for the in-person and virtual workshop attendees.

As part of the NCA5 process, an independent validation was conducted of the two statistically downscaled climate data products used in the NCA5 report. The goal was to assess consistency among these products under a suite of metrics and diagnostics, and to inform the careful use of these data products in decision-making. In general, the two products were found to be largely consistent with each other. The minor differences between products are attributed to climate variability, downscaling methodology and observational uncertainty. The full report, Validation of LOCA2 and STAR-ESDM Statistically Downscaled Products, also provides recommendations to users. The research was funded by DOE’s Office of Biological and Environmental Research, Earth and Environmental Systems Sciences Division and is available here.
