Tree Ring Chronology from Preparation Canyon State Park, Iowa

NOAA NCEI archives a tree-ring chronology dataset from Preparation Canyon State Park in Iowa, United States. The data covers a period from 236 to -27 calendar years before present, representing over 250 years of paleoclimatic proxy information. This dataset was published by the NOAA National Centers for Environmental Information in 1977.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate climate models by comparing the proxy tree-ring record from Iowa with instrumental data.
• Analyze long-term environmental trends in the region by examining the year-by-year tree-ring growth indices.
• Study the frequency of climatic extremes or disturbances recorded in the tree-ring series over its 250+ year span.

Strengths

• Data spans over 250 years, from 236 to -27 calendar years BP.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
• Provides a geographically specific paleoclimate proxy record for Iowa.

Limitations

• The dataset's last update was in 1977, indicating potential staleness in metadata or access methods.
• Specific sample size, replication, and measurement parameters are unknown from the provided description.
• Geographic coverage is limited to a single site in Iowa, reducing regional generalizability.
