Colorado Tree-Ring Width Chronology from 450 to -30 BP

Tree-ring width measurements from Mount Goliath, Colorado provide a 480-year climate proxy record ending around 1980 CE. NOAA's National Centers for Environmental Information archives this paleoclimatology dataset as part of the World Data Service. The data was last updated in the NOAA system in 1980.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for Colorado using the tree-ring width time-series.
• Calibrate climate models by comparing the 480-year proxy record from Mount Goliath with instrumental data.
• Analyze growth trends and extreme events within the chronology to study forest resilience over centuries.
• Integrate this Colorado site chronology into continental-scale networks like PAGES 2k for broader climate reconstructions.

Strengths

• Provides a continuous 480-year climate proxy record from 450 to -30 calendar years BP.
• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.
• Specifically contributes to the continental-scale PAGES North America 2K climate reconstruction initiative.

Limitations

• Temporal coverage ends around 1980 CE, lacking recent decades for contemporary climate comparison.
• Data is from a single geographic site (Mount Goliath, Colorado), limiting spatial representativeness.
• The exact sample size, measurement methods, and potential measurement noise are not detailed in the provided metadata.
