Chilean Tree Ring Chronology from Caramavida (510 to -25 BP)

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Caramavida site in Biobio, Chile. The chronology covers 535 years, from 510 to -25 calendar years before present. NOAA National Centers for Environmental Information (NCEI) provides this data, last updated in 1975.

Use Cases

• Reconstruct past temperature or precipitation using annual tree-ring width measurements.
• Calibrate radiocarbon dates by aligning this chronology with other regional tree-ring records.
• Analyze climate periodicity over 535 years from the ring width time-series.
• Study long-term ecological responses in Chilean forests from growth patterns.

Strengths

• 535-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Data recency is low, with a last update date of 1975.
• Sample size and replication details for the tree-ring series are unknown.
• Geographic coverage is limited to a single site in Biobio, Chile.
