Tree ring width data from the Niwot Ridge site in Colorado, USA, used for paleoclimate studies. The chronology spans 657 years, from 620 to 37 years before present (BP). This archived study was contributed by Graybill and is maintained by NOAA's National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate climate models by comparing the ring width time-series against instrumental records.
- Analyze long-term climate trends and extreme events in the Colorado region over the 657-year period.
Strengths
- Chronology covers a 657-year time period (620 to 37 BP).
- Data is archived and curated 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 site (Niwot Ridge, Colorado).
- Sample size and replication statistics for the underlying tree cores are unknown.
