Sequoia Tree Ring Chronology From 70 to -40 BP

110 calendar years of tree ring data from the Colony Mill site in Sequoia National Park, California. The dataset was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1990.

Use Cases

• Reconstruct past climate conditions by analyzing tree ring width chronologies.
• Calibrate radiocarbon dating models using the dated tree ring series.
• Study long-term ecological growth patterns of giant sequoias in a specific park location.

Strengths

• Covers a 110-year time period from 70 to -40 calendar years before present.
• Sourced from NOAA NCEI, an authoritative repository for paleoclimate data.

Limitations

• Data recency is low, with a last update recorded in 1990.
• Specific sample size, measurement parameters, and file formats are unknown.
