Beaver Creek Ponderosa Pine Tree-Ring Chronology from 380 to -36 BP

416-year tree-ring chronology from Ponderosa Pine (PIPO) at Beaver Creek, Arizona, provides a proxy record of past climate. Data coverage spans from 380 to -36 calendar years before present, indicating it includes years both before and after the 1950 baseline. The NOAA National Centers for Environmental Information archives this paleoclimatology study, originally published in 1986.

Use Cases

• Reconstruct past precipitation or drought indices by analyzing the tree-ring width series.
• Calibrate the tree-ring chronology against instrumental climate records from the Arizona region.
• Study the growth patterns of Ponderosa Pine (PIPO) in response to climate over a 416-year period.
• Compare this site chronology (ITRDB AZ513) with other tree-ring series to assess regional climate signals.

Strengths

• Covers a 416-year time period (380 to -36 BP).
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection via NOAA NCEI.
• Provides a site-specific chronology for a defined species (PIPO) and location (Beaver Creek, Arizona).

Limitations

• Temporal coverage ends at -36 BP (1986 CE), making the most recent data nearly 40 years old.
• Limited to a single tree species and geographic site, reducing broad climatic inferences.
• Lack of column details prevents assessment of data density or ancillary measurements.
