Argentine Tree Ring Chronology From 250 to 24 BP

A 274-year tree ring chronology from Laguna Terraplen, Chubut, Argentina, covering the period from 250 to 24 calendar years before present. The dataset contains parameters related to tree ring growth and is archived by NOAA's World Data Service for Paleoclimatology. Data was published in 1974.

Use Cases

• Reconstruct past climate conditions (e.g., temperature, precipitation) using tree ring width parameters.
• Calibrate and validate climate models for the Southern Hemisphere with a 274-year proxy record.
• Analyze growth anomalies in the tree ring series to identify extreme historical climate events.
• Compare this Argentine chronology with other Southern Hemisphere tree ring datasets for hemispheric climate patterns.

Strengths

• Covers a 274-year time period (250 to 24 BP), providing a multi-century climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 24 years BP, lacking recent modern climate data for comparison.
• Geographic scope is limited to a single site in Chubut, Argentina.
• Data was last updated in 1974, potentially using outdated collection or analysis methods.
