California Tree Ring Chronology From 640 to 30 BCE

670-year tree ring chronology from the Hager Basin Reservoir site in California, providing paleoclimate data. The dataset was archived by NOAA's World Data Service for Paleoclimatology and originates from a study by Holmes. Data coverage spans from 640 to 30 calendar years before present.

Use Cases

• Reconstruct past temperature and precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the chronology data with instrumental records from the California region.
• Analyze the frequency and severity of historical droughts from the ring width variations.
• Establish cross-dating references for other paleoclimate archives in the western United States using this site chronology.

Strengths

• 670-year temporal coverage provides a long-term climate record.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service.

Limitations

• The dataset's last update was in 1980, indicating potential staleness and lack of modern reanalysis.
• Specific sample size, measurement parameters, and replication statistics are unknown from the provided metadata.
