Tree Ring Chronology From Yosemite National Park 110-Year Record

NOAA/WDS Paleoclimatology archives a tree ring chronology from the South Fork Tuolumne Creek in Yosemite National Park, California. The dataset covers a 110-year period from 70 to -40 calendar years before present (BP), measured from Abies concolor (White Fir) trees. It was published by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the California region.
• Analyze growth patterns and environmental stress events recorded in the Abies concolor (ABCO) ring sequences.
• Establish a dated timeline for ecological events in Yosemite National Park over the 110-year period.

Strengths

• Data spans a 110-year period (70 to -40 BP), providing a multi-decadal climate record.
• Sourced from a protected national park (Yosemite), likely reducing modern anthropogenic disturbance signals.
• Archived by the authoritative NOAA World Data Service for Paleoclimatology, ensuring formal curation.

Limitations

• Temporal coverage is relatively short for paleoclimate studies at only 110 years.
• Data is geographically limited to a single creek site within California.
• The dataset was last updated in 1990, indicating potential staleness in metadata or availability.
