Challenges Coordinating Regional Climate Model Simulations over North America: Ongoing Learned from NA-CORDEX-CMIP6.

This presentation will provide a detailed overview of the latest developments in the second phase of the NA-CORDEX initiative, which focuses on dynamically downscaling CMIP6 simulations. CORDEX is an international effort organized by the World Climate Research Programme (WCRP) to produce coordinated sets of regionally-downscaled climate projections worldwide for better understanding of local/regional climate change and variability and evaluation of downscaling models and techniques.

NA-CORDEX is the North American component of the global CORDEX initiative. The first phase of NA-CORDEX downscaled CMIP5 and has been widely used in climate impacts and adaptation studies and assessments across a broad range of topics including resource management, agriculture, ecosystems, water supply, infrastructure resilience, and more.

Here we will provide a status update on NA-CORDEX-CMIP6, including an overview of planned and completed simulations, simulation protocols and output requirements, data archiving and access plans, and information on how to contribute and/or receive updates. In particular we will discuss the unique challenges that arise from developing simulations over such a large domain and balancing the needs/interests of multiple institutions and end-user-needs.

We invite anyone who is interested in using dynamically downscaled climate data to stop by our poster to discuss data wants/needs as well as ideas for expanding funding to build the most useful archive.
