Mount Rainier Tree Ring Chronology from 100 to 42 BCE

Tree ring width measurements from subalpine fir trees at Mount Rainier, Washington, used for paleoclimate reconstruction. The chronology covers 142 years, from 100 to 42 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate radiocarbon dating curves using the precisely dated tree ring chronology.
• Study the response of subalpine fir (ABLA) growth to climate stressors over a 142-year period.
• Compare this local chronology with other regional tree ring datasets to identify broad climate patterns.

Strengths

• Chronology spans 142 years, providing a multi-decadal climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.

Limitations

• Temporal coverage is limited to a specific 142-year window in the distant past.
• Geographic scope is restricted to a single site at Mount Rainier, Washington.
• Data record has not been updated since its archival in 1992.
