Tree Ring Chronology From Sequoia National Park

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Pillars site in Sequoia National Park, California. The data covers a 110-year period from 70 to -40 calendar years before present. This dataset was published by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation from tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology with other paleoclimate proxy records.
• Analyze growth patterns and environmental stress events recorded in the tree ring series.
• Study the response of giant sequoia (ABMA) growth to historical climatic shifts over the 110-year period.

Strengths

• Data spans a 110-year time period (70 to -40 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Geographic location is precisely defined as Sequoia National Park, California.

Limitations

• Dataset is relatively small, covering only one site and a short 110-year chronology.
• Data is temporally stale, with a last recorded update in 1990.
• Specific sample depth, measurement statistics, and raw measurement values are not detailed in the provided description.
