Argentine Tree Ring Chronology from Caviahue Spanning 530 Years

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Caviahue site in Neuquén, Argentina. The dataset provides parameters for dendroclimatological analysis covering the period from 506 to -24 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
• Analyze growth trends and extreme events (e.g., volcanic eruptions) recorded in the ring sequences.
• Establish a dated chronology for archaeological or geological studies in the Neuquén province.

Strengths

• Time series spans 530 calendar years (506 to -24 BP), providing a multi-century record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -24 BP (approximately 1974 CE), with no updates since the original study publication.
• The single-site geographic focus (Caviahue, Argentina) limits regional representativeness.
• Specific parameters, sample depth, and measurement statistics are not detailed without accessing full metadata.
