Wynoochee Falls Tree Ring Chronology for Paleoclimate Reconstruction

563 years of tree-ring width measurements from 533 to -30 calendar years before present, providing a proxy climate record. The dataset contains parameters for tree-ring analysis from Tsuga mertensiana (TSME) trees at Wynoochee Falls, Washington. It is an archived paleoclimatology study from the NOAA National Centers for Environmental Information's World Data Service.

Use Cases

• Reconstruct past temperature or precipitation anomalies from annual tree-ring width measurements.
• Calibrate climate models using the multi-century proxy record for the Washington region.
• Analyze growth trends and extreme climatic events within the Tsuga mertensiana chronology.
• Cross-date and validate other tree-ring chronologies from the Pacific Northwest using this ITRDB series.

Strengths

• Covers a 563-year time period from 533 to -30 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a species-specific (Tsuga mertensiana) chronology for a defined geographic site.

Limitations

• Temporal coverage ends at -30 BP (approximately 1980 CE), with no recent updates.
• Sample size (number of tree cores) and replication statistics are unknown.
• Geographic coverage is limited to a single site in Washington State.
