A 480-year tree-ring width chronology from a Pseudotsuga menziesii (Douglas fir) site at San Juan Hill, Washington, United States. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the PAGES North America 2K project. The temporal coverage spans from 450 to -30 calendar years before present.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width time-series.
- Calibrate and validate climate models using the high-resolution proxy data from the 'calendar years before present (BP)' timeline.
- Study the growth response of Pseudotsuga menziesii (PSME) to historical climate events recorded in the ring-width measurements.
- Compare this local chronology from the 'Washington, United States Of America' location with other regional records in the PAGES 2K network.
Strengths
- Provides a 480-year continuous chronology from 450 to -30 calendar years BP.
- Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset's last known update was in 1980, indicating potential staleness and lack of recent maintenance.
- Sample size, replication, and specific site details are unknown from the provided metadata.
