VEMAP 2 Alaska Historical and Future Climate Scenarios

VEMAP Phase 2 provides gridded monthly climate scenarios for Alaska at 0.5-degree resolution. The dataset includes historical estimates from 1922-1996 and future projections from 1997-2100. This work was developed by the Vegetation/Ecosystem Modeling and Analysis Project and is distributed by NASA.

Use Cases

• Validating regional climate models using historical temperature and humidity grids.
• Projecting future ecosystem water stress using potential evapotranspiration estimates.
• Analyzing long-term solar radiation trends for renewable energy potential studies.
• Studying changes in vapor pressure and relative humidity for atmospheric research.

Strengths

• Provides a continuous 179-year temporal record from 1922 to 2100.
• Offers spatially consistent gridded data at 0.5-degree resolution for Alaska.
• Includes multiple key climate variables: temperature, radiation, humidity, and evapotranspiration.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Conflicting last update dates exist: one source shows 2026-03-12, others show a placeholder date of 2100-12-31.
• License is ambiguously listed as 'other-license-specified', requiring further investigation.
