Ellen Cockran Hollow Tree Ring Chronology from Arkansas

Tree ring data from Arkansas, United States, spans a period from 186 to -26 calendar years before present (BP), representing a chronology that extends into the future from the collection date. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. It was last updated in the NCEI system in 1976.

Use Cases

• Calibrating regional climate models using the tree-ring width time series as a proxy for past precipitation or temperature.
• Analyzing growth anomalies in the ring width series to identify extreme drought or wet periods in the Arkansas region.
• Cross-dating this chronology (ITRDB AR067) with other regional tree-ring series to validate and extend climate reconstructions.

Strengths

• Covers a 212-year period (186 to -26 BP) of environmental record.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• The data was last updated in 1976, indicating it is a static, legacy dataset with no recent revisions.
• Specific parameters, measurement methods, and sample depth are not detailed in the provided description, requiring metadata review.
