Arizona Tree-Ring Chronology From 250 to 37 Years Before Present

NOAA's Paleoclimatology archive provides a tree-ring chronology for Arizona, United States. The data coverage spans from 250 to 37 calendar years before present (BP). This dataset was archived by NOAA National Centers for Environmental Information in 1987.

Use Cases

• Reconstructing past climate variables like precipitation or temperature using tree-ring width measurements.
• Calibrating radiocarbon dating models by correlating tree-ring sequences with the documented time period.
• Analyzing long-term ecological responses to climate shifts by examining growth patterns in the chronology.

Strengths

• Temporal coverage spans 287 years (250 to -37 BP).
• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1987.
• Specific sample size, column details, and measurement parameters are not provided in the input.
