Sequoia National Park Tree Ring Chronology from 71 to -40 BP

California's Sequoia National Park provides a tree ring chronology covering 111 years from 71 to -40 calendar years before present. The dataset contains parameters related to tree ring growth and was archived by NOAA's National Centers for Environmental Information. This paleoclimatology study was last updated in 1990.

Use Cases

• Reconstruct past climate conditions like temperature or precipitation using tree ring width measurements.
• Calibrate radiocarbon dating or establish chronological markers for the region using the dated ring series.
• Analyze growth anomaly years within the 111-year sequence to identify extreme historical environmental events.

Strengths

• Time series covers a specific 111-year period (71 to -40 BP).
• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, last updated in 1990.
• Small temporal coverage of 111 years limits long-term climate trend analysis.
• Specific sample size, measurement parameters, and data granularity are unknown from the description.
