Blue Mountain Subalpine Fir Tree Ring Chronology for Washington

Tree ring width measurements from subalpine fir (Abies lasiocarpa) trees in the Blue Mountains of Washington, USA. The dataset provides a chronology spanning 133 calendar years, from 93 to -40 years before present, archived by NOAA NCEI's World Data Service for Paleoclimatology. This study was published as part of the International Tree-Ring Data Bank in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the time-series of tree ring width measurements.
• Calibrate climate models for the Pacific Northwest using the 133-year dendrochronological record.
• Study growth patterns of subalpine fir (Abies lasiocarpa) in response to historical environmental events captured in the ring data.
• Cross-date and validate other tree-ring chronologies from the region using this established ITRDB series (WA126).

Strengths

• Chronology spans 133 calendar years, providing a multi-decadal climate record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Temporal coverage ends 40 years after present (BP), limiting analysis of the most recent climate period.
• Sample size and replication statistics for the underlying tree cores are unknown.
• Geographic coverage is limited to a single site in the Blue Mountains, Washington.
