Lake Ahquabi Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from Lake Ahquabi State Park in Iowa. The data provides a proxy climate record spanning from 376 to -30 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, last updated in 1980.

Use Cases

• Reconstructing historical temperature or precipitation anomalies from tree-ring width measurements.
• Calibrating regional climate models using the multi-century chronology spanning over 400 years.
• Analyzing growth patterns and climate sensitivity of tree species at the Lake Ahquabi site.
• Cross-dating this chronology with other ITRDB (International Tree-Ring Data Bank) records for broader regional analysis.

Strengths

• Data covers a significant time span of over 400 years, from 376 to -30 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology and the ITRDB network.

Limitations

• Temporal coverage ends at -30 BP, indicating the dataset is not updated with recent centuries.
• Geographic scope is limited to a single site in Iowa, limiting broader regional conclusions.
• Specific sample size, measurement parameters, and data formats are not provided in the metadata.
