Spillway Lake in Yosemite National Park provides a tree-ring width chronology for climate reconstruction. The dataset covers a 787-year period from 750 to 37 BCE. It was archived by NOAA's National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
- Calibrate regional climate models by comparing the ring-width chronology with known historical climate events.
- Analyze long-term climate trends in California by examining the variance in annual ring-width measurements.
- Establish a dated proxy record for the Sierra Nevada region from the 750-37 BCE time period.
Strengths
- 787-year continuous time-series from 750 to 37 BCE.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1987, indicating potential methodological staleness.
- Specific sample depth, replication statistics, and measurement precision are not provided in the input.
