Chilean Tree Ring Width Chronology from Piuchue Island

433 years of tree ring width data from Piuchue Island, Chiloe, Chile, covering the period from 396 to -37 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by Roig and associated with the International Tree-Ring Data Bank. It was archived by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past precipitation (PLUV) levels using the tree ring width (ITRDB CHIL018) chronology.
• Calibrate the tree ring width series against known climate events within the 433-year temporal range.
• Analyze growth trends and anomalies in the Piuchue Island tree ring record to infer climatic stressors.
• Compare this Chilean chronology (ITRDB CHIL018) with other Southern Hemisphere tree ring datasets for hemispheric climate analysis.

Strengths

• Covers a 433-year period from 396 to -37 BP, providing a multi-century climate record.
• Part of the authoritative NOAA/WDS Paleoclimatology and International Tree-Ring Data Bank (ITRDB) archives.

Limitations

• The dataset's last update was in 1987, indicating it is a static, historical archive without recent additions.
• Specific sample depth, measurement statistics, and raw measurement data are not provided in the available description.
