Dolliver Memorial State Park Tree Ring Chronology from 265 to -31 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from Dolliver Memorial State Park in Iowa. The chronology covers a 296-year period from 265 to -31 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this data in 1981.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation from tree ring width measurements.
• Calibrate regional climate models by comparing the tree ring chronology with other proxy records for the time period.
• Analyze growth anomalies in the tree ring series to identify past drought or disturbance events at the site.
• Establish a dated chronology for archaeological or geological studies in Iowa using the provided calendar years BP.

Strengths

• Covers a 296-year time period from 265 to -31 calendar years BP.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, last updated in 1981, potentially lacking modern reanalysis.
• Geographic coverage is limited to a single state park site in Iowa, limiting regional generalizability.
• Specific parameters, sample depth, and measurement methodologies are not detailed in the provided description.
