Chilean Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from Santa Lucia, Chiloe Island, Chile, used as a proxy for past climate conditions. The chronology covers 498 years, from 461 to -36 calendar years before present. Data is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct historical precipitation (PLUV parameter) for southern Chile using the tree ring width chronology.
• Calibrate the tree ring chronology against other paleoclimate proxies using its 498-year time span.
• Analyze long-term climate trends in South America by examining the annual-resolution ring width data.
• Validate climate model simulations for the Chilean region using the dated proxy record.

Strengths

• Chronology spans 498 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last documented update in 1986.
• Geographic coverage is limited to a single site (Santa Lucia, Chiloe Island).
• Specific parameters and measurement details require consulting external metadata.
