Blue Mountain Tree Ring Chronology for Climate Reconstruction

Tree ring width measurements from Abies lasiocarpa (ABLA) trees at the Blue Mountain Low site in Washington state. The chronology covers 140 years, from 100 to -40 calendar years before present, providing a proxy for historical climate conditions. Data is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation using the tree ring width time-series as a climate proxy.
• Calibrate the tree ring chronology against known climate events within the 140-year period.
• Analyze growth patterns in Abies lasiocarpa (ABLA) for ecological studies in Washington state.
• Compare this site's chronology (ITRDB WA125) with other regional tree-ring datasets to assess spatial climate patterns.

Strengths

• Data spans a continuous 140-year period (100 to -40 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a specific tree species (Abies lasiocarpa) and site location (Blue Mountain Low, Washington).

Limitations

• Temporal coverage is limited to 140 years, which is short for some paleoclimate analyses.
• The dataset was last updated in 1990, indicating potential staleness in metadata or availability.
• Geographic scope is restricted to a single site in Washington, limiting broad regional conclusions.
