Colorado Tree-Ring Width Chronology from 750 to 37 BCE

Tree-ring width measurements from the Collins Gulch site in Colorado, United States. The chronology covers the period from 750 to 37 years before present (BP). Data is archived by NOAA's World Data Service for Paleoclimatology under the PAGES North America 2K initiative.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Colorado using the tree-ring width time-series.
• Calibrate and validate climate model simulations for the last millennium with the annually-resolved proxy data.
• Analyze the frequency and severity of historical droughts in the Southwestern US from the ring-width record.
• Study the growth response of PIED (Pinus edulis) trees to climatic forcing over a ~700-year period.

Strengths

• Provides a ~700-year annually-resolved climate proxy record (750 to 37 BP).
• Data is part of the standardized PAGES North America 2K network for continental-scale analysis.

Limitations

• Temporal coverage ends in 37 BP, providing no data for the modern instrumental period.
• Represents a single geographic site (Collins Gulch, Colorado), limiting spatial representativeness.
• The dataset was last updated in 1987, potentially lacking modern reanalysis or quality refinements.
