Washington Tree Ring Chronology from Box Canyon

343 calendar years of tree ring data from Box Canyon, Washington, compiled by NOAA NCEI's Paleoclimatology program. The chronology spans from 343 to -26 years before present, providing a proxy record for past climate conditions. This archived study was last updated in 1976.

Use Cases

• Analyze annual tree ring width variations as a proxy for past temperature or precipitation patterns.
• Cross-date the chronology with other regional tree ring series to validate climate reconstructions.
• Calibrate the tree ring time series against instrumental climate records for the period after -26 BP.
• Study growth anomalies in Pinus ponderosa (PIPO) specimens to identify extreme climatic events.

Strengths

• Provides a 343-year chronology for climate reconstruction.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Data freshness is low, last updated in 1976.
• Specific sample size, measurement parameters, and data formats are unknown.
• Geographic coverage is limited to a single site in Washington.
