Nine Eagles State Park Tree Ring Chronology from 278 to -32 BP

Tree ring width measurements from a site in Iowa, United States, used for climate reconstruction. The chronology covers a period from 278 to -32 calendar years before present. This archived paleoclimatology study was published by NOAA NCEI's World Data Service for Paleoclimatology in 1982.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate regional climate models using the dated tree ring chronology as a proxy record.
• Study the response of tree growth to historical climate events within the specific geographic location of Iowa.
• Cross-date and validate other tree ring chronologies from the North American Midwest using this ITRDB series.

Strengths

• Data spans 310 years, from 278 to -32 calendar years BP.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• Temporal coverage is limited to a single 310-year period, not continuous to the present.
• Data is geographically limited to a single site (Nine Eagles State Park, Iowa).
• The dataset was last updated in 1982, indicating potential staleness in metadata or methods.
