Chilean Tree Ring Chronology from Alto de las Mesas

Tree ring width measurements from the Alto de las Mesas site in Chile provide a 179-year chronology for paleoclimate analysis. The data covers the period from 154 to -25 calendar years before present (BP). This archived study is maintained by NOAA's World Data Service for Paleoclimatology and was last updated in 1975.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using tree ring width as a proxy.
• Calibrate climate models by comparing the chronology with known historical climate events.
• Analyze growth patterns to infer environmental stress periods within the 179-year time span.

Strengths

• Data spans a continuous 179-year chronology (154 to -25 BP).
• Archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1975, indicating potential methodological or metadata staleness.
• Geographic coverage is limited to a single site (Alto de las Mesas) in Chile.
• Specific measurement parameters and sample depth are unknown from the provided description.
