NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Crater Mountain, Washington, USA. The chronology covers a period from 252 to -39 calendar years before present. It was published by NOAA NCEI and last updated in the repository in 1989.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width series.
- Calibrate climate models using the dated proxy record spanning several centuries.
- Study local environmental events, like volcanic eruptions or droughts, by identifying marker years in the ring-width data.
- Cross-date other tree-ring collections from the region using the established chronology.
Strengths
- Time series covers a 291-year period (252 to -39 BP).
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last repository update in 1989.
- Specific sample size (number of tree cores) and measurement parameters are unknown from the description.
