Wet Mountains Tree Ring Chronology from 614 to 47 BC

Tree ring width measurements from Douglas fir (PSME) in Colorado's Wet Mountains provide a 661-year climate proxy. NOAA's National Centers for Environmental Information archives this dendrochronological dataset for paleoclimate research. The chronology was published in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology with instrumental records for validation.
• Analyze growth response patterns to specific climatic events recorded within the 661-year time series.
• Establish cross-dating references for other tree ring studies in the central Colorado region.

Strengths

• Covers a 661-year time period from 614 to 47 BC.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset has not been updated since its publication in 1997.
• Specific sample size, replication statistics, and measurement details are not provided in the input.
