Arkansas Tree Ring Chronology from 239 to 84 Years BP

Tree ring width measurements from the Lancaster Cabin and Barn site in Arkansas, USA, provide a 155-year climate proxy record. The dataset covers the period from 239 to 84 calendar years before present, compiled by researcher Stahle. It is archived by NOAA's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past precipitation or temperature by analyzing the annual tree_ring_width chronology.
• Calibrate regional climate models using the 155-year proxy record from the Arkansas site.
• Compare the JUVI (likely Juniperus virginiana) species' growth response with other regional tree-ring series.
• Study environmental events like droughts by identifying narrow ring sequences within the time-series.

Strengths

• Data covers a continuous 155-year period (239 to 84 BP).
• Archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Includes precise geographic location for the tree collection site in Arkansas, USA.

Limitations

• Sample size (number of tree cores or series) is unknown, limiting statistical confidence.
• Temporal coverage is relatively short (155 years) for some long-term climate studies.
• The last documented update was in 1866, indicating potential metadata staleness.
