VEMAP2: Gridded Monthly Climate Data for the Conterminous U.S., 1895-2100

VEMAP2 provides monthly mean model-predicted climate data from 1895 to 1993 and future projections to 2100. Data are gridded for the Conterminous United States at 0.5 x 0.5 degree spatial resolution, processed from two global climate model scenarios. The collection was provided by the Vegetation/Ecosystem Modeling and Analysis Project at NCAR.

Use Cases

• Modeling future temperature changes based on the CCCma and HadCM2 climate scenarios.
• Analyzing precipitation ratio projections for the 1961-1990 baseline period.
• Studying ecosystem responses using derived radiation and humidity fields.
• Benchmarking climate models against historical data from 1895 to 1993.

Strengths

• Includes a long historical time series from 1895 to 1993.
• Provides future climate projections from two distinct model scenarios (CCCma-CGCM1 and HadCM2).
• Data is gridded at a consistent 0.5 x 0.5 degree spatial resolution for the Conterminous U.S.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to nasa_earthdata, focusing solely on the Conterminous United States.
