Iowa Tree Ring Chronology from 296 to -30 BP

Tree ring width measurements from a site in Iowa, United States, provide a climate proxy record spanning 326 years from 296 to -30 calendar years before present. The data is archived by the NOAA National Centers for Environmental Information World Data Service for Paleoclimatology. This specific chronology was published in 1980.

Use Cases

• Reconstruct past climate conditions like temperature or precipitation by analyzing the tree ring width time-series.
• Calibrate radiocarbon dating or other chronological methods using the dated tree ring sequence.
• Compare the growth pattern from this Iowa site with other North American tree ring chronologies to identify regional climate signals.
• Study the response of local tree species to documented historical events or climatic shifts within the 326-year period.

Strengths

• 326-year continuous time-series provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Record covers a relatively short period for paleoclimate studies, limited to 326 years.
• Geographic scope is restricted to a single site in Iowa, limiting broad spatial analysis.
• Data is temporally stale, with the last update recorded in 1980.
