Tree Ring Chronology from Las Bateas, Coahuila, Mexico (170 to -49 BP)

Tree ring width chronology data from Pinus strobiformis (PSME) trees at the Las Bateas site in Coahuila, Mexico. The dataset provides a paleoclimate record covering 219 years from 170 to -49 calendar years before present. This archived study was contributed by Villanueva-Diaz and is hosted by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past precipitation or drought indices using the tree ring width chronology as a proxy.
• Calibrate climate models by comparing the tree ring time-series data with known historical climate events.
• Analyze growth patterns and climate sensitivity of Pinus strobiformis (PSME) in Coahuila, Mexico.
• Study long-term ecological trends by examining the 219-year record of tree growth for environmental shifts.

Strengths

• Time series covers a continuous 219-year period (170 to -49 BP).
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Specific geographic location (Coahuila de Zaragoza, Mexico) and tree species (PSME) are documented.

Limitations

• Data is temporally stale, with a last update recorded in 1999.
• The raw sample size (number of tree cores or series) is unknown, limiting assessment of statistical robustness.
• Geographic coverage is limited to a single site (Las Bateas), reducing regional representativeness.
