Missouri Tree-Ring Width Chronology from 750 to 37 BCE

A 787-year tree-ring width chronology from the Allred Lake Natural Area in Missouri, USA, covering the period from 750 to 37 BCE. The dataset is part of the NOAA/WDS Paleoclimatology archive and the PAGES North America 2K initiative, created for climate reconstruction studies. It was contributed by the author Stahle and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing the annual tree-ring width time-series.
• Calibrate and validate climate models using the precisely dated 787-year proxy record from Missouri.
• Study ecological responses to historical climate events by examining growth anomalies within the ring-width chronology.
• Contribute to continental-scale climate syntheses like PAGES 2k by integrating this site-specific chronology.

Strengths

• Provides a 787-year continuous proxy record for climate analysis.
• Part of the authoritative PAGES North America 2K network for standardized continental climate reconstruction.
• Hosted and curated by NOAA's World Data Service for Paleoclimatology, ensuring archival stability.

Limitations

• Data is temporally stale, with a last update recorded in 1987.
• Limited geographic scope to a single site (Allred Lake, Missouri), reducing regional representativeness.
• Lacks metadata on sample depth (number of cores/trees), preventing assessment of chronology robustness.
