Santa Catalina Mountains Tree Ring Chronology 424-18 BP

A 442-year tree-ring chronology from the Santa Catalina Mountains in Arizona, spanning from 424 to 18 calendar years before present. The dataset contains parameters for tree-ring width measurements, archived by NOAA's World Data Service for Paleoclimatology. Data was published or last updated in 1968.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree-ring width series.
• Analyze long-term growth trends and environmental stress events recorded in the PSME (Ponderosa Pine) ring sequences.
• Calibrate and validate climate models for the Arizona region with proxy data from 424-18 BP.
• Study the frequency of extreme climatic events, such as droughts, indicated by narrow ring formations.

Strengths

• Covers a 442-year time period (424 to -18 BP)
• Geographically specific to the Santa Catalina Mountains in Arizona
• Part of the authoritative NOAA/NCEI Paleoclimatology archive

Limitations

• Temporal coverage ends 18 years before present, lacking recent centuries
• Sample size and replication statistics for individual tree cores are unknown
• Data publication date (1968) suggests methodologies may be outdated
