Tree-ring width measurements from a site in Iowa, United States, used for paleoclimate studies. The chronology covers a 97-year period from 72 to -25 calendar years before present (BP). This archived dataset is provided by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct historical temperature or precipitation anomalies for Iowa using the tree-ring width time-series.
- Calibrate the tree-ring chronology against other regional proxy records using its annual resolution and temporal coverage.
- Analyze growth response to specific climatic events within the 97-year period covered by the ring-width data.
Strengths
- Data covers a specific 97-year period (72 to -25 BP), providing a focused temporal snapshot.
- Sourced from NOAA NCEI's World Data Service, an authoritative repository for paleoclimate data.
Limitations
- The dataset's temporal coverage is relatively short (97 years) for long-term climate trend analysis.
- Data is geographically limited to a single site in Iowa, limiting regional representativeness.
- The last update recorded was in 1975, indicating the metadata may be stale.
