Tree ring width measurements from Chile, covering a 315-year period from 270 to 45 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The data was last updated in the repository in 1995.
Use Cases
- Calibrate climate proxy models using tree ring width as an indicator of past temperature or precipitation.
- Reconstruct annual climate conditions for southern South America over a 315-year historical period.
- Validate hemispheric climate reconstructions by comparing this Chilean chronology with other regional tree ring records.
- Analyze growth anomalies in tree ring sequences to identify volcanic or climatic events impacting the region.
Strengths
- Covers a specific 315-year period from 270 to 45 calendar years BP.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is limited to a pre-industrial period ending 45 years BP.
- Data repository was last updated in 1995, indicating potential staleness in metadata or access methods.
- Geographic coverage is restricted to a single location in Chile.
