NASA NEX-DCP30-CMIP6 Bioclimatic Variables for Conterminous USA

John B. Kim calculated a suite of twenty bioclimatic variables from NASA NEX-DCP30-CMIP6 downscaled climate projections. The data includes outputs from thirty global climate models for SSP2-45 and SSP5-85 scenarios across historical (1970-1999), mid-century (2035-2064), and late-century (2070-2099) periods at 30 arc-second resolution. A historical reference dataset was also created using the Parameter-elevation Regressions on Independent Slopes Model (PRISM).

Use Cases

• Modeling climate refugia for plant species based on projected bioclimatic variables.
• Analyzing shifts in species distribution based on monthly, seasonal, and annual climate metrics.
• Comparing historical and future climate conditions for ecological niche modeling.
• Studying the impact of different emission scenarios (SSP2-45 vs. SSP5-85) on bioclimatic envelopes.

Strengths

• Includes data from thirty global climate models, providing an ensemble view.
• Covers three distinct time periods (historical, mid-century, late-century) and two future scenarios.
• Provides a high spatial resolution of 30 arc-seconds for the conterminous United States.
• Includes a historical reference dataset calculated from PRISM for validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset size is listed as 0.0 B, indicating limited scope or a placeholder entry.
• Data is specific to the conterminous United States, limiting global applicability.
