Tree-ring width measurements from Colorado provide a climate proxy record spanning 787 years, from 750 to -37 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific study was last updated in 1987.
Use Cases
- Reconstruct historical temperature or precipitation anomalies in Colorado using the tree-ring width time-series.
- Calibrate the tree-ring width chronology against other paleoclimate proxies for the North America 2K network.
- Analyze the frequency and severity of drought events in the Southwestern United States over the 787-year period.
- Validate climate model simulations of past centuries using the empirically derived tree-ring record.
Strengths
- 787-year continuous time-series from 750 to -37 BP.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1987.
- Geographic coverage is limited to a single location in Colorado, USA.
- The dataset contains only the tree-ring width parameter, lacking complementary environmental variables.
