California Tree Ring Chronology From 626 To 42 BCE

Tree ring width measurements from the Deer Creek site in California provide a 668-year chronology from 626 to 42 BCE. This paleoclimate dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies for California by calibrating tree ring width measurements against modern climate records.
• Analyze the frequency and severity of drought events in the region over the 668-year period using annual growth ring sequences.
• Cross-date and validate other tree ring chronologies from the western United States using this established SEGI/ITRDB CA725 series.
• Study the response of local tree species to volcanic eruptions or other short-term climate forcings visible in the ring width data.

Strengths

• 668-year continuous chronology from 626 to 42 BCE provides a long-term baseline.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data record ends over 2000 years ago, limiting analysis of more recent climate periods.
• Specific sample size, replication statistics, and measurement parameters are not provided in the basic description.
