We will introduce a newly developed, dynamically downscaled dataset that covers the North American continent and the surrounding ocean, namely Argonne Downscaled Data Archive (ADDA). ADDA consists of two components. The first component comprises 20-year reanalysis driven regional climate model simulations for the current climate, and the second component involves Earth system model (ESM) driven simulations for hindcast and future projections. ADDA is available at two spatial and temporal resolutions, with ADDA v1 at a spatial and temporal resolution of 12 km and 3hours; and ADDA v2 at 4 km and hourly interval. ADDA v1 has been evaluated comprehensively, and utilized in various applications, including (1) regional resiliency assessment program (RRAP) funded by Department of Homeland Security for Portland, Maine, Texas, and California; (2) risk assessments to critical infrastructures from wildfires (Brown et al., 2021; Yu et al., 2023), droughts (Gamelin et al., 2022), inland and coastal flooding (Pal et al., 2023; Pringle et al., 2021), extreme heat/cold, and wind gusts, with support from AT&T, Pacific Gas & Electricity, New York Power Authority, and Northern Illinois ComEd; (3) assessment of climate change-induced risks for soil and groundwater contamination and waste disposal cells over Department of Energy (DOE)’s 118 legacy sites distributed across the United States (Wainwright et al. 2022). ADDA v2 covers even a larger domain, including the entire Alaska and Caribbean islands, providing extensive opportunities to assess the historical and future local impact of natural hazards (e.g., tropical/extratropical cyclones, atmospheric rivers) in a changing climate. A risk assessment framework is developed to translate the extremely large datasets to the most useful information for guiding the industry partners for their climate change mitigation plan. A climate portal, named Climate Risk and Resiliency (ClimRR), to share ADDA has been recently created and continues to be advanced with support from Federal Emergency Management Agency (FEMA). With more advanced computing resource available at Argonne Leadership Computing Facilites, the team is developing extra high resolution (1km) simulations over North America using Graphic Processing Unit (GPU) accelerated Weather Research and Forecasting model.
