Tree ring width chronology data from a site in the O'Higgins Region of Chile. The dataset provides paleoclimate proxy records covering a period from 382 to -25 calendar years before present (BP). This archived study is maintained by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
- Calibrate climate proxy models using the dated time series from 382 to -25 BP.
- Study climate extremes and events by identifying narrow or wide ring features within the chronology.
- Compare this Southern Hemisphere tree ring record with other paleoclimate archives for hemispheric synchronization.
Strengths
- Time series coverage spans 407 years, from 382 to -25 calendar years BP.
- Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -25 BP (approximately 1975 CE), with no more recent updates indicated.
- Sample size, replication, and species information for the tree ring collection are not specified in the provided metadata.
