Chilean Tree Ring Chronology from Santa Lucia (461 to -36 BP)

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Santa Lucia site in Chile. The dataset provides a time series for paleoclimate reconstruction covering 497 years, from 461 to -36 calendar years before present. It was contributed by author Roig and is managed by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past precipitation (PLUV parameter) from the Santa Lucia tree ring width chronology.
• Analyze long-term climate trends in Chile using the 497-year time series of tree ring parameters.
• Calibrate regional climate models by comparing the ITRDB CHIL017 proxy record with other paleoclimate archives.
• Study inter-annual to centennial-scale climate variability from the dated tree ring sequence.

Strengths

• Time series spans 497 calendar years (461 to -36 BP).
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
• Includes specific geographic location details for the study site in Chile.

Limitations

• Dataset is temporally stale, last updated in 1986.
• Sample size and replication depth of the tree ring chronology are unknown.
• Geographic coverage is limited to a single site (Santa Lucia) in Chile.
