California Tree-Ring Width Chronology from Boles Creek

NOAA's Paleoclimatology archive provides a tree-ring width chronology from the Boles Creek site in California. The dataset covers 787 years, from 750 to 37 years before present, for reconstructing past climate conditions. It was published by NOAA National Centers for Environmental Information in 1987.

Use Cases

• Reconstruct annual precipitation or temperature anomalies for California using the tree-ring width time-series.
• Analyze the frequency and severity of historical droughts by identifying narrow ring sequences in the chronology.
• Calibrate climate models by comparing the tree-ring proxy record with instrumental data from the region.
• Study long-term ecological responses to climate change by examining growth trends over the 787-year period.

Strengths

• 787-year temporal coverage provides a long-term climate proxy record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1987.
• Geographic scope is limited to a single site (Boles Creek) in California.
