Tree Ring Chronology From Yosemite National Park

NOAA/WDS Paleoclimatology provides a tree-ring chronology for the Tuolumne Grove in Yosemite National Park. The dataset covers a time period from 70 to -40 calendar years before present. It is archived by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation from tree-ring width measurements.
• Analyze growth anomalies in the tree-ring series to identify extreme historical climate events.
• Calibrate the chronology against other proxy records using the provided calendar years before present (BP) timeline.
• Study the response of Pinus lambertiana (PILA) to environmental changes over a 110-year period.

Strengths

• Data spans a 110-year period (70 to -40 BP), providing a century-scale record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last updated date of 1990-01-01.
• Sample size and specific row/column counts are unknown, limiting reproducibility assessment.
• Geographic coverage is limited to a single grove in California.
