Tree ring width data from the Gin Flat site in Yosemite National Park, California, provides a climate proxy record. The chronology covers a 110-year period from 70 to -40 calendar years before present. This archived paleoclimatology study was published by NOAA's National Centers for Environmental Information in 1990.
Use Cases
- Reconstruct past temperature or precipitation anomalies for the Yosemite region using the tree-ring width chronology.
- Calibrate the Gin Flat site chronology against other regional tree-ring records to validate climate signals.
- Analyze the growth response captured in the ring widths to infer specific climatic events within the 110-year BP period.
Strengths
- Data spans a 110-year period (70 to -40 BP)
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology
Limitations
- Temporal coverage is relatively short for climate reconstruction studies
- Data is geographically limited to a single site in California
- The dataset was last updated in 1990, indicating potential staleness
