NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Hidden Valley, Colorado. The chronology covers 127 years, from 90 to -37 calendar years before present. It was published by NOAA NCEI and last updated in 1987.
Use Cases
- Reconstruct historical temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate climate models by comparing the proxy tree ring data with instrumental records for the region.
- Analyze climate sensitivity and growth response by correlating ring-width indices with known climatic events.
- Establish a regional master chronology for cross-dating other tree ring samples from the Colorado area.
Strengths
- 127-year continuous chronology for climate proxy analysis.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short (127 years) for long-term climate trend analysis.
- Dataset is geographically limited to a single site (Hidden Valley, Colorado).
- Data was last updated in 1987 and may lack modern methodological refinements.
