Washington state tree ring width measurements from the Rainy Pass 2 site, providing a paleoclimate record. The chronology covers 228 calendar years, from 202 to -26 years before present. Data is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies from tree ring width measurements.
- Calibrate climate models by comparing modeled past conditions with the tree ring proxy record.
- Analyze the frequency of extreme climate events, such as droughts, within the 228-year chronology.
- Cross-date and validate other tree ring chronologies from the Cascade region using this established series.
Strengths
- 228-year chronology providing a multi-century climate proxy.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Limited geographic scope to a single site (Rainy Pass 2) in Washington.
- Temporal coverage is relatively short for some paleoclimate studies at 228 years.
- Data last updated in 1976, indicating potential staleness and lack of recent methodological review.
