Washington Tree Ring Chronology From 503 BC

NOAA/WDS Paleoclimatology archives a tree ring chronology for the North Fork White Creek site in Washington, USA. The dataset provides annual tree ring parameters covering a 533-year period from 503 to 30 BC. It was contributed by researcher Graumlich and is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
• Calibrate climate models by comparing the tree ring proxy record with known historical climate events.
• Analyze growth trends and extreme events (e.g., droughts) visible in the ring parameter time series.
• Establish a dated chronology (ITRDB WA050) for cross-dating with other regional tree ring studies.

Strengths

• Covers a 533-year time period from 503 to 30 BC.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Data is temporally stale, last updated in 1980.
• Specific parameters, sample size, and measurement methods are not detailed in the provided metadata.
