Tree Ring Chronology from Sierra Madre, Mexico (230 BP to -15 BP)

Tree ring width data from Pinus ponderosa (PIPO) trees at the Rancho Escondido site in the Sierra Madre, Chihuahua, Mexico. The chronology covers a 245-year period from 230 to -15 calendar years before present. This archived study was contributed by Stokes and is maintained by NOAA's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct annual precipitation or drought indices for northern Mexico using tree ring width as a proxy.
• Calibrate regional climate models by comparing the tree ring chronology with known historical climate events.
• Analyze growth anomalies in the ring width series to identify volcanic eruptions or other disturbances during the covered period.
• Establish a dated master chronology for Pinus ponderosa in the Sierra Madre to cross-date other samples.

Strengths

• Data covers a 245-year period, providing a multi-century climate record.
• Sourced from NOAA's authoritative World Data Service for Paleoclimatology archives.

Limitations

• Temporal coverage ends at -15 BP (15 AD), making the record temporally stale for modern climate studies.
• Geographic scope is limited to a single site (Rancho Escondido) in Chihuahua.
