787-year tree-ring width chronology from Colorado, USA, covering the period from 750 to -37 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by the Woodhouse research group. It was last updated in the NOAA system in 1987.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Colorado using the annual tree-ring width series.
- Calibrate climate proxy models by comparing the ring-width chronology with instrumental climate records.
- Analyze the frequency and severity of historical drought events in the region from the growth anomaly patterns.
- Study ecological resilience and growth responses of Pseudotsuga menziesii (PSME) to past climatic stresses.
Strengths
- 787-year temporal coverage provides a long-term climate proxy record.
- Data is archived and maintained by the authoritative NOAA National Centers for Environmental Information.
Limitations
- The dataset's last known update was in 1987, indicating potential staleness and lack of recent curation.
- Specific sample size, replication statistics, and measurement precision are unknown from the provided metadata.
