Santa Lucia Tree Ring Width Data for Climate Reconstruction

340 calendar years of tree-ring width data from Chile, covering the period from 304 to -36 years before present. This paleoclimatology dataset is part of the PAGES LOTRED-SA version and is archived by NOAA's National Centers for Environmental Information. The data was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies from the tree-ring width time-series.
• Calibrate regional climate models by comparing the tree-ring proxy record with instrumental data.
• Analyze long-term climate trends in Chile over the 340-year period covered by the chronology.
• Validate other paleoclimate proxies by correlating the Santa Lucia tree-ring width series with other regional records.

Strengths

• Covers a specific 340-year time period (304 to -36 BP).
• Part of the standardized PAGES LOTRED-SA regional paleoclimate database.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data last updated in 1986, potentially lacking modern re-calibration or newer methodological refinements.
• Single geographic location (Chile) limits spatial representativeness for broader regional analysis.
• Unknown sample size (number of tree cores) and replication, which affects chronology robustness.
