434-year tree ring chronology from Central Alaska, spanning from 394 to -40 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1990. It provides parameters related to tree ring growth for paleoclimate studies.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Central Alaska using the tree ring width parameter.
- Calibrate the chronology against other proxy records using the provided calendar year BP time scale.
- Analyze growth trends and extreme events within the 434-year record for ecological studies.
Strengths
- 434-year temporal coverage provides a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data recency is limited, with a last update recorded in 1990.
