EPA Dynamically Downscaled Ensemble (EDDE) Version 2: 12km U.S. Climate Projections

1985-2014 and 2025-2100 are the historical and future periods covered by this dataset of 3D atmospheric conditions for the contiguous United States. The U.S. Environmental Protection Agency produced this collection of physics-based modeled data, which is dynamically downscaled from global climate models at a 12-kilometer horizontal grid spacing with hourly increments. Data are provided in netCDF 4 format, adhering to Climate and Forecasting (CF) compliance standards for interoperability.

Use Cases

• Modeling regional climate change impacts based on high-resolution (12km) downscaled projections.
• Analyzing future atmospheric conditions under the SSP 3-7.0 scenario for the contiguous U.S.
• Studying hourly variations in 3D atmospheric data for applications in air quality or flood risk assessment.
• Comparing dynamically downscaled outputs from the MPI-ESM1-2-HR model with other climate datasets.

Strengths

• High spatial resolution of 12 kilometers for the contiguous United States.
• Hourly temporal increments provide detailed time-series data.
• Data adheres to Climate and Forecasting (CF) compliance standards for enhanced portability.
• Covers a long future projection period from 2025 to 2100 under a defined emission scenario.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
