Likely Mountain Tree Ring Chronology for California Paleoclimate

Tree ring data from the Likely Mountain site in California provides a 327-year chronology from 297 to -30 calendar years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under its World Data Service. The data was originally published in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
• Calibrate the chronology against other proxy records using the provided calendar years before present (BP) time axis.
• Analyze long-term climate trends for California by examining the full 327-year time series.
• Validate climate model simulations of the past using this site-specific proxy dataset.

Strengths

• 327-year continuous chronology covering a significant pre-instrumental period.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -30 BP, providing no data for the most recent two millennia.
• The dataset's age (published 1980) means it may lack modern analytical metadata and updates.
