450 to -30 calendar years before present of tree-ring width data from Colorado, USA. This paleoclimatology dataset is part of the NOAA NCEI World Data Service for Paleoclimatology and the PAGES North America 2K initiative. The associated study type is Tree Ring, archived by NOAA NCEI.
Use Cases
- Reconstructing past temperature or precipitation anomalies using the tree-ring width time-series as a climate proxy.
- Calibrating regional climate models by comparing the ring-width chronology with instrumental records for the overlapping period.
- Analyzing long-term ecological growth trends in high-altitude Colorado forests from the annual ring-width measurements.
- Contributing to continental-scale climate syntheses like PAGES 2K by providing a North American tree-ring site chronology.
Strengths
- Time-series spans 480 years from 450 to -30 calendar years BP, providing multi-century coverage.
- Data is archived and standardized by NOAA NCEI's World Data Service for Paleoclimatology, an authoritative repository.
Limitations
- Temporal coverage ends at -30 BP (~1980 CE), making the record potentially stale for recent climate studies.
- Geographic coverage is limited to a single site (Hermit Lake, Colorado), limiting regional generalizability.
