Tree ring width data from subalpine fir trees at Klahhane Ridge in Washington state, USA. The chronology covers a 140-year period from 100 to -40 calendar years before present. This paleoclimatology study was archived by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using the tree ring width time series.
- Calibrate the tree ring chronology against known climate events within the 140-year BP period.
- Analyze growth patterns in subalpine fir (ABLA) trees from a specific geographic location in Washington.
Strengths
- Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Covers a defined 140-year time period in calendar years before present.
Limitations
- The dataset's temporal coverage is relatively short for long-term climate trend analysis.
- Data is geographically limited to a single ridge site in Washington state.
- The last known update was in 1990, indicating potential staleness.
