Walnut Canyon Tree Ring Chronology from 270 to -36 BP

NOAA's Paleoclimatology archive provides a tree ring chronology from Walnut Canyon, Arizona, United States. The data covers the period from 270 to -36 calendar years before present. This study was archived by the NOAA National Centers for Environmental Information in 1986.

Use Cases

• Reconstruct past climate variables like precipitation or temperature using tree ring width measurements.
• Calibrate radiocarbon dates or other chronological models using the established tree ring chronology.
• Analyze growth patterns and environmental stress events recorded in the tree ring series.
• Compare this local chronology with regional tree ring datasets to study spatial climate patterns.

Strengths

• Time series coverage spans 306 years, from 270 to -36 calendar years BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1986.
• The specific sample size, measurement parameters, and data granularity are not provided in the description.
• Geographic coverage is limited to a single site in Walnut Canyon, Arizona.
