NEX-DCP30-CMIP6: Downscaled Climate Projections for CONUS

Daily, monthly, and annual downscaled CMIP6 climate projections over the contiguous United States at 30-arcsecond horizontal resolution. The dataset includes variables for maximum temperature, minimum temperature, precipitation, and vapor pressure. It is produced by the National Aeronautics and Space Administration (NASA) Ames Research Center.

Use Cases

• Project regional temperature extremes based on downscaled maximum and minimum temperature data.
• Model future hydrological cycles based on downscaled precipitation and vapor pressure projections.
• Assess climate change impacts on specific ecosystems using high-resolution spatial data over CONUS.
• Validate and compare regional climate models against the downscaled CMIP6 ensemble.

Strengths

• High spatial resolution at 30-arcsecond for detailed regional analysis over CONUS.
• Includes four key climate variables: maximum temperature, minimum temperature, precipitation, and vapor pressure.
• Provides data at daily, monthly, and annual temporal aggregations for flexibility in analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale machine learning tasks.
• Last update date is unknown; freshness unverified.
