Tunnel Creek Tree Ring Chronology for Pacific Silver Fir

406 years of tree-ring width data from 376 to -30 calendar years before present, providing a proxy for historical climate conditions. This paleoclimatology dataset is curated by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was archived and last updated in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies from tree-ring width chronologies.
• Calibrate climate models using proxy data from the Pacific Silver Fir (PSME) species.
• Analyze long-term growth trends and responses to environmental stressors in Washington state forests.
• Compare this ITRDB WA054 chronology with other regional tree-ring records for spatial climate analysis.

Strengths

• Covers a 406-year time period for long-term trend analysis.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection from NOAA/NCEI.

Limitations

• Data recency is low, with a last update in 1980, potentially missing modern methodological refinements.
• Geographic coverage is limited to a single site (Tunnel Creek) in Washington, USA.
