Washington State Tree Ring Chronology from 297 to -25 BP

A tree-ring chronology from Lucky Point, Washington, United States, covering the period from 297 to -25 calendar years before present. The dataset contains parameters related to tree rings and is archived by NOAA's World Data Service for Paleoclimatology. Data was published by NOAA NCEI in 1975.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree-ring width parameters.
• Calibrate climate models by comparing the chronology with other proxy records for the time period.
• Analyze long-term growth trends of Pinus ponderosa (PIPO) trees at the Lucky Point site.

Strengths

• Covers a specific 322-year period (297 to -25 BP) for climate analysis.
• Part of the authoritative NOAA/WDS Paleoclimatology archive and ITRDB (WA010).

Limitations

• Data is temporally stale, with a last update recorded in 1975.
• The geographic scope is limited to a single site (Lucky Point, Washington).
• Specific sample size (row count) and measurement parameters are unknown.
