NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Windy Ridge site in Colorado, USA. The dataset provides annual growth measurements covering the period from 900 to -35 calendar years before present. It was created by researcher Graybill and published through the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
- Calibrate climate models using the precisely dated proxy record spanning 935 years.
- Study extreme climate events, such as droughts, by identifying narrow ring sequences in the chronology.
- Compare this Colorado site chronology with other regional tree-ring datasets to assess spatial climate patterns.
Strengths
- Time series spans 935 calendar years, from 900 to -35 BP.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last recorded update in 1985.
- Geographic scope is limited to a single site (Windy Ridge) in Colorado.
