Wolverton Sequoia Tree Ring Chronology For Paleoclimate Analysis

NOAA/WDS Paleoclimatology archives a tree ring chronology from giant sequoia (ABCO) trees in Sequoia National Park, California. The dataset covers a 110-year period from 70 to -40 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1990.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate climate models by comparing the chronology's growth patterns against known climate events.
• Analyze the growth response of giant sequoias to environmental changes over a 110-year span.
• Establish a regional baseline for comparing modern tree growth with pre-industrial conditions.

Strengths

• Data spans a 110-year time period (70 to -40 BP).
• Sourced from a protected national park environment, reducing local anthropogenic noise.

Limitations

• Dataset is temporally stale, last updated in 1990.
• Specific sample size (row count) and measurement parameters are unknown.
• Geographic coverage is limited to a single site in California.
