NOAA/WDS Paleoclimatology archives a tree-ring chronology from Gin Flat in Yosemite National Park, California, focusing on white fir (ABCO). The data provides a time series covering the period from 70 to -41 calendar years before present (BP). This dataset was published by NOAA National Centers for Environmental Information in 1991.
Use Cases
- Reconstruct historical temperature or precipitation anomalies by analyzing the tree-ring width chronology.
- Calibrate climate models using the dated proxy record from 70 to -41 BP.
- Study the growth response of white fir (ABCO) to past environmental conditions in the Sierra Nevada.
Strengths
- Time series spans 111 calendar years (from 70 to -41 BP).
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last update date of 1991.
- Specific sample depth, measurement parameters, and raw data formats are not provided in the description.
