NASA Downscaled CMIP5 Climate Projections for the United States

NASA Earth Exchange Downscaled Climate Projections (NEXDCP30) provide high-resolution climate data for studying climate change impacts at local to regional scales in the United States. The dataset is intended for scientific research to enhance understanding of future climate patterns. It is produced by NASA and hosted on the NASA Center for Climate Simulation portal.

Use Cases

• Analyzing projected changes in surface air temperature for regional climate vulnerability assessments.
• Modeling future 24-hour precipitation amounts to inform hydrological and flood risk studies.
• Conducting high-resolution climate impact research at the scale of neighborhoods or communities.
• Serving as input for downscaled climate models focusing on the United States.

Strengths

• Data is produced by NASA, a leading authority in Earth and climate science.
• Projections are downscaled to a high 30 arc-second resolution for localized analysis.
• Dataset is hosted on multiple official platforms (Data.gov, NASA Earthdata), indicating institutional support.

Limitations

• Specific row counts, file sizes, and complete column lists are not provided across sources.
• Sources conflict on the last updated date (2026-03-13 vs 2099-12-31), casting doubt on metadata accuracy.
• License is specified as 'other-license-specified' with restrictions on non-scientific use.
