Tree ring width measurements from McCurtain County, Oklahoma, used for paleoclimate reconstruction. The chronology covers a period of 358 years, from 326 to -32 calendar years before present. Data is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology and was last updated in 1982.
Use Cases
- Reconstruct past climate variables like precipitation or temperature using the tree ring width time-series.
- Calibrate climate models by comparing the tree ring chronology with instrumental records from the region.
- Analyze the frequency and severity of historical drought events indicated by narrow ring sequences.
- Study the growth response of trees to climate over a 358-year period before present.
Strengths
- Data spans a continuous 358-year period (326 to -32 BP).
- Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends 32 years before present (1950 CE), limiting analysis of the most recent climate period.
- Geographic scope is limited to a single county (McCurtain) in Oklahoma.
- Data was last updated in 1982, indicating potential staleness in metadata or availability of newer versions.
