Mexican Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width data from the Sierra de la Laguna region of Mexico, used for paleoclimate analysis. The chronology spans 164 years, from 117 to -47 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information and published in 1997.

Use Cases

• Reconstruct past precipitation or temperature anomalies by analyzing the annual tree ring width series.
• Calibrate the chronology against other regional proxy records using the provided calendar year (BP) timeline.
• Study climate extremes and their frequency in pre-Hispanic Mexico through patterns in the ring width data.

Strengths

• Chronology covers a 164-year period (117 to -47 BP), providing a multi-decadal climate record.
• Data is curated and archived by the NOAA World Data Service for Paleoclimatology, a authoritative source.

Limitations

• Temporal coverage is relatively short (164 years) compared to millennial-length tree ring chronologies.
• Data is geographically limited to a single site (Sierra de la Laguna, Mexico), limiting regional analysis.
• The dataset was last updated in 1997, and more recent versions or extensions may be unavailable.
