Arkansas Tree-Ring Chronology from 171 to -30 BP

Tree-ring width measurements from Arkansas provide a 201-year climate proxy record spanning from 171 to -30 calendar years before present. This paleoclimate dataset was archived by NOAA's National Centers for Environmental Information and the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width time-series.
• Calibrate climate models using the 201-year proxy record to validate simulations for the pre-instrumental era.
• Study the frequency of drought events in Arkansas by identifying narrow ring sequences in the chronology.
• Perform cross-dating with other regional tree-ring chronologies using the shared time-series data.

Strengths

• Covers a 201-year time period (171 to -30 BP) for climate proxy analysis.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 201 years, which is relatively short for some paleoclimate studies.
• Data is geographically restricted to a single location in Arkansas, USA.
• The dataset was last updated in 1980, indicating it may not reflect the most recent methodological standards.
