NOAA/WDS Paleoclimatology provides a tree ring chronology from the Timber Gap Lower site in California. The dataset covers the period from 900 to 37 calendar years before present (BP). This archived study is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using annual tree-ring width measurements.
- Calibrate radiocarbon dating or synchronize timelines by cross-dating the tree-ring chronology with other proxy records.
- Analyze long-term ecological responses to climate events using the site-specific growth record spanning centuries.
Strengths
- Time series spans 937 years (900 to 37 BP), providing a long-term environmental record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1987.
- Geographic coverage is limited to a single site (Timber Gap Lower) in California.
- Specific parameters, measurement methods, and sample sizes are not detailed in the provided description.
