Mount Rainier Tree Ring Chronology from 100 to 42 BCE

Tree ring width measurements from subalpine fir trees near Mount Rainier, Washington, USA, provide a paleoclimate record. The dataset covers 142 years, from 100 to 42 calendar years before present, and is archived by NOAA's National Centers for Environmental Information. Data was published through the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate climate models using the precisely dated 142-year chronology from subalpine fir (Abies lasiocarpa).
• Study forest growth patterns and resilience by examining the inter-annual variability in ring measurements.
• Compare this local chronology with other regional tree ring datasets to identify broader climate signals.

Strengths

• 142-year continuous, precisely dated chronology from 100 to 42 BCE.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis at 142 years.
• Geographic scope is limited to a single site near Mount Rainier, Washington.
• Data record was last updated in 1992, indicating no recent additions or revisions.
