Tree ring width data from the South Fork Tuolumne Creek in Yosemite National Park provides a proxy climate record. The chronology covers 111 years, from 70 to -41 calendar years before present. This archived paleoclimatology study was published by NOAA NCEI's World Data Service in 1991.
Use Cases
- Reconstruct past temperature or precipitation variations using the tree ring width time-series.
- Calibrate climate models by comparing the proxy tree ring chronology with instrumental records.
- Analyze the frequency of climatic extremes, such as droughts, within the 111-year record.
- Study the growth response of Abies magnifica (ABMA) trees to historical environmental changes.
Strengths
- 111-year continuous chronology from 70 to -41 BP.
- Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Specific geographic location documented: South Fork Tuolumne Creek, Yosemite National Park, California.
Limitations
- Dataset is temporally stale, last updated in 1991.
- Sample size (number of tree cores) and replication details are unknown.
- Limited to a single species (Abies magnifica) at one site, reducing regional representativeness.
