Tree Ring Chronology From Antonito Site In Colorado

266 calendar years of tree ring data from the Antonito site in Colorado, United States, provide a proxy record for past climate conditions. The dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was last updated in 1964.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate the chronology against other proxy records for the 266-year period.
• Analyze growth response patterns in Pinus strobiformis (PSME) trees to environmental stressors.
• Validate climate model simulations for the Colorado region using the dated proxy series.

Strengths

• Covers a 266-year time series from 266 to -14 calendar years before present.
• Provides a geographically specific record from a known site in Colorado.

Limitations

• The dataset's last update was in 1964, indicating potential staleness in metadata or methods.
• Sample size and replication depth for the tree ring series are unknown.
