Tree Ring Chronology from Arkansas for Paleoclimate Analysis

NOAA's Paleoclimatology archive provides a tree ring chronology from Pencil Bluff, Arkansas. The data covers a 262-year period from 221 to -41 calendar years before present. This record was published by NOAA National Centers for Environmental Information in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
• Calibrate climate models by comparing the chronology with other regional proxy records.
• Analyze the frequency of extreme climatic events within the 262-year time series.
• Study ecological responses to climate change by examining growth patterns in the tree ring data.

Strengths

• Data spans a continuous 262-year period for climate trend analysis.
• Sourced from the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1991, making it temporally stale for recent analyses.
• Geographic scope is limited to a single site in Arkansas, reducing regional representativeness.
• Specific parameters like ring width measurements or sample depth are not detailed in the provided metadata.
