California Tree Ring Width Chronology from Lundy Lake

787 years of tree-ring width data from Lundy Lake, California, spanning from 750 to -37 calendar years before present. The dataset was produced by Graumlich and archived by NOAA's World Data Service for Paleoclimatology. It was last updated in 1987.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width time-series.
• Calibrate climate models by comparing the proxy data from this chronology with simulated past climates.
• Analyze long-term climate trends and extreme events in California over the 787-year period covered by the ring-width data.
• Cross-date and validate other paleoclimate records from the region using the established tree-ring chronology.

Strengths

• Covers a 787-year time period (750 to -37 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Provides a continuous, annually-resolved proxy record for climate reconstruction.

Limitations

• Data is temporally stale, with a last update recorded in 1987.
• Geographic coverage is limited to a single site at Lundy Lake, California.
• The specific sample depth and replication statistics for the chronology are unknown from the provided metadata.
