Washington State Tree-Ring Width Chronology from 450 to -30 BP

Tree-ring width data from a Pseudotsuga menziesii (Douglas-fir) site at Elliot Creek in Washington, USA, covering the period from 450 to -30 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was last updated in the system in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Washington State by analyzing the tree-ring width time-series.
• Calibrate the tree-ring width chronology against other regional paleoclimate proxies to validate climate models.
• Study the growth response of Pseudotsuga menziesii to climatic events over a ~480-year period ending around 30 years BP.
• Perform cross-dating analysis using the ring-width data to establish a precise calendar date for each annual ring.

Strengths

• Time-series covers approximately 480 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Dataset provides a specific geographic location (Washington, USA) and tree species (Pseudotsuga menziesii).

Limitations

• Temporal coverage ends at -30 BP (approximately 1980 CE), lacking recent decades for contemporary climate analysis.
• Data is from a single site (Elliot Creek), limiting spatial representativeness for the broader region.
• The last known update was in 1980, suggesting the metadata and access methods may be outdated.
