Segelson Pass Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring chronology from Segelson Pass, Washington. The dataset covers a 655-year period from 629 to -26 calendar years before present. NOAA National Centers for Environmental Information (NCEI) compiled and published this study in 1976.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width measurements.
• Calibrate climate models using the 655-year proxy record from PSME (Douglas-fir) tree species.
• Study regional climate events in Washington State by cross-dating the Segelson Pass chronology with other records.
• Analyze growth patterns and environmental stressors captured in the tree ring parameters.

Strengths

• Covers a 655-year time series (629 to -26 BP), providing a long-term proxy record.
• Sourced from NOAA NCEI's authoritative World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1976.
• Specific sample size, column details, and measurement parameters are not provided in the metadata.
• Geographic coverage is limited to a single site (Segelson Pass, Washington).
