Tree ring width measurements from Colorado, USA, used for climate reconstruction. The chronology covers 857 years, from 843 to 14 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width as a proxy.
- Calibrate climate models by comparing the tree ring chronology against instrumental records for the overlapping period.
- Analyze long-term growth trends and resilience by examining the ring width time series for the PSME (Pinus strobiformis) species.
- Study extreme climatic events, such as droughts, by identifying narrow ring sequences within the 857-year record.
Strengths
- 857-year continuous chronology from 843 to 14 BP
- Data is curated and archived by the authoritative NOAA NCEI World Data Service
Limitations
- Sample size and replication depth for individual years are unknown
- Data record ends at 14 BP, lacking overlap with most modern instrumental climate records
- Geographic coverage is limited to a single site in Colorado
