102-year tree ring chronology from a site in Colorado, United States, covering the period from 70 to -32 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the Schweingruber study. It was last updated in the NOAA system in 1982.
Use Cases
- Calibrate regional climate models using the tree ring width time-series as a proxy for past temperature or precipitation.
- Analyze growth anomaly patterns in the ring width series to identify extreme climatic events like droughts.
- Cross-date this chronology with other ITRDB series to validate and extend regional tree ring networks.
- Study the response of tree growth to climatic forcing during the transition from BCE to CE periods covered by the data.
Strengths
- Covers a 102-year period from 70 to -32 BP, providing a continuous chronology.
- Part of the authoritative International Tree Ring Data Bank (ITRDB) collection curated by NOAA.
Limitations
- The dataset is temporally stale, with a last update date of 1982.
- The sample size (number of tree cores or series) is unknown, which limits assessment of statistical robustness.
- Geographic coverage is limited to a single site in Colorado.
