430 to -46 calendar years before present (BP) of tree ring data from California, USA. The dataset is part of the NOAA/WDS Paleoclimatology archive and is associated with the Tree Ring study type. It was archived by NOAA National Centers for Environmental Information, with a last known update in 1996.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
- Calibrate climate models using the long-term, precisely dated proxy record from 430 to -46 BP.
- Study ecological disturbance events, such as fires or droughts, recorded in the ring series from Yosemite National Park.
- Perform cross-dating analysis to validate and extend the chronology using the PIAL (Presumably Pinus albicaulis) species data.
Strengths
- Time series spans 476 years (430 to -46 BP), providing a multi-century climate proxy.
- Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).
Limitations
- Data is temporally stale, with a last known update in 1996.
- Specific sample size, measurement parameters, and replication statistics are not provided in the input.
