Chilean Tree Ring Chronology from 564 to -25 BP

NOAA/WDS Paleoclimatology provides a tree ring chronology from the Nalcas - ARAR - ITRDB CHIL006 site in Chile. The dataset covers the period from 564 to -25 calendar years before present (BP). It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate radiocarbon dating or other chronological methods by aligning the tree ring series with known time periods.
• Analyze growth anomalies in the ring width data to identify volcanic eruptions or other environmental disturbances.
• Compare this Chilean tree ring chronology with other regional series to study large-scale climate patterns like ENSO.

Strengths

• Time series spans 589 years, from 564 to -25 BP.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1975, indicating potential methodological staleness.
• Specific parameters, sample depth, and measurement details are not provided in the basic description.
