Tree ring width measurements from the Muir Grove in California provide a 592-year climate proxy record. The data, archived by NOAA's World Data Service for Paleoclimatology, was last updated in 1991. It is part of the International Tree-Ring Data Bank (ITRDB) collection for site CA713.
Use Cases
- Reconstruct past precipitation and temperature anomalies in California using annual tree ring width as a proxy.
- Calibrate regional climate models by comparing the 592-year tree ring chronology with known historical climate events.
- Analyze growth patterns and potential climate stressors for Sierra Nevada conifers over six centuries.
- Correlate the Muir Grove chronology (ITRDB CA713) with other North American tree ring series to identify broad climate patterns.
Strengths
- Covers a substantial 592-year time period from 551 to 41 BCE.
- Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology and the ITRDB.
Limitations
- Data is temporally stale, with a last recorded update in 1991.
- Specific sample size, measurement methods, and potential site disturbances are not detailed in the provided metadata.
