North Slope Arizona Tree Ring Chronology from 230 BP

Tree ring width chronology data from the North Slope site in Arizona, United States. The data coverage spans from 230 to -37 calendar years before present. This archived paleoclimatology study is provided by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width time-series.
• Calibrate the chronology against known climate events using the provided calendar years before present (BP) index.
• Analyze growth anomalies in the Pinus ponderosa (PIPO) species record for ecological studies.

Strengths

• Time-series coverage spans 267 calendar years (from 230 to -37 BP).
• Data is archived and curated by the NOAA World Data Service for Paleoclimatology, an authoritative source.

Limitations

• Data was last updated in 1987, making it temporally stale for contemporary climate analysis.
• The specific sample size (number of tree cores or sites) and measurement parameters are not provided in the description.
