Tree ring width data from Colorado provides a proxy climate record spanning 787 years, from 750 to -37 calendar years before present. The NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology archives this dataset. The data was last updated in 1987.
Use Cases
- Reconstruct historical temperature or precipitation anomalies using the tree-ring width time-series.
- Calibrate climate models by comparing the proxy tree-ring width record against instrumental data for the Colorado region.
- Analyze the frequency of extreme climate events, such as droughts, through statistical analysis of the ring width chronology.
- Study long-term ecological responses to climate change by examining growth trends in the tree-ring series.
Strengths
- Time-series spans 787 years, providing a long-term climate proxy.
- Data is archived and curated by the authoritative NOAA NCEI 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 in Colorado, USA.
- Sample size and replication details for the tree-ring series are unknown.
