Colorado tree-ring width data from the NOAA National Centers for Environmental Information provides a paleoclimate record. The time series covers 787 years, from 750 to -37 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology and last updated in 1987.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Colorado using the tree-ring width time series as a climate proxy.
- Calibrate the tree-ring width chronology against instrumental climate records to validate its sensitivity.
- Analyze the frequency and severity of historical drought periods within the 787-year record.
- Compare this Colorado chronology with other regional tree-ring datasets to study spatial climate patterns.
Strengths
- 787-year continuous time series provides a long-term climate context.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data recency is low, with a last update recorded in 1987.
- The geographic scope is limited to a single site in Colorado, United States.
