Argentine Tree Ring Chronology Spanning 326 Years

Tree ring data from the Peninsula Brunswick site in Argentina provides a chronology from 288 to -38 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was last updated in 1988.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate regional climate models by comparing the tree ring chronology with other proxy records.
• Analyze growth anomalies within the chronology to identify specific historical environmental events.

Strengths

• Provides a continuous 326-year chronology from calendar years 288 BP to -38 BP.
• Data originates from NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1988, indicating potential staleness in metadata or curation.
• Specific parameters, sample size, and measurement details are not provided in the basic description.
