Tree ring data from Baker Ski, Washington, spans 645 years from 619 to -26 calendar years before present, documenting historical climate conditions. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. This specific chronology was published in 1976.
Use Cases
- Reconstruct annual temperature or precipitation anomalies using tree-ring width measurements.
- Calibrate radiocarbon dating by aligning this chronology with other regional series.
- Analyze climate forcing events like volcanic eruptions or droughts through growth anomaly patterns in the ring data.
- Validate climate model simulations of past centuries against this observed proxy record.
Strengths
- Time series covers 645 consecutive years.
- Data is part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Data is from a single site (Baker Ski, Washington), limiting regional representativeness.
