107-year tree ring width chronology from Hueicolla, Los Lagos, Chile, covering 82 to -25 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1975. It provides parameters for dendroclimatological analysis.
Use Cases
- Reconstruct past precipitation or temperature using the tree ring width parameter as a climate proxy.
- Calibrate climate models by comparing the 107-year chronology with instrumental records.
- Analyze growth anomalies in the ring width series to identify extreme historical climate events.
- Correlate the Chilean tree ring series with other Southern Hemisphere paleoclimate records.
Strengths
- 107-year continuous chronology providing a multi-decadal climate record.
- Data archived and standardized by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -25 BP, limiting analysis of the most recent centuries.
- Single geographic location in Los Lagos, Chile, restricts spatial representativeness.
- Last metadata update was in 1975, indicating potential staleness in documentation.
