Colorado Tree Ring Width Chronology from 750 to -37 BP

Tree ring width measurements from Colorado provide a climate reconstruction spanning 787 years, from 750 to -37 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information as part of its Paleoclimatology World Data Service. The study was last updated in 1987.

Use Cases

• Reconstruct historical temperature or precipitation anomalies for Colorado using the tree-ring width time-series.
• Calibrate climate models by comparing the 787-year tree-ring chronology with other proxy records.
• Analyze long-term growth trends and extreme events in Pinus strobiformis (PSME) trees from site CO646.
• Validate the PAGES North America 2K continental-scale climate reconstruction with this local site data.

Strengths

• 787-year continuous chronology from 750 to -37 BP provides long-term context.
• Data originates from NOAA NCEI, an authoritative repository for paleoclimate records.

Limitations

• The dataset's last update was in 1987, making it temporally stale for modern methodological comparisons.
• Specific sample depth, replication statistics, and measurement uncertainty metrics are not provided in the summary.
