Jackson Meadow Reservoir Tree-Ring Width Chronology from 750 BC

Tree-ring width data from the Jackson Meadow Reservoir site in California, United States, covering 787 years from 750 to -37 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The associated NCEI study type is Tree Ring, and the data was last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate the tree-ring width series against instrumental climate records to validate climate models.
• Analyze the frequency and severity of historical droughts in California from the ring-width variations.
• Compare this chronology with other PAGES North America 2K Version datasets to study regional climate patterns.

Strengths

• Covers a 787-year period, providing a long-term climate record.
• Part of the standardized PAGES North America 2K Version network, ensuring methodological consistency for continental-scale analysis.
• Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at 37 BC, with no data for the modern era.
• The dataset was last updated in 1987, potentially lacking modern reanalysis or corrections.
• Geographic scope is limited to a single site in California, limiting broad spatial analysis.
