Cerro Baraja Tree Ring Chronology From 574 BC

Tree ring width measurements from a Mexican site provide a 618-year climate proxy record. The dataset covers the period from 574 to 43 years before present, ending just before the Common Era. It is an archived paleoclimatology study from the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past drought severity by analyzing annual tree_ring_width variations.
• Calibrate regional climate models using the 618-year proxy time_series for validation.
• Study volcanic or climatic events around 43 BP by identifying anomalies in the ring_width chronology.
• Compare this Mexican site's growth patterns with other ITRDB chronologies to assess spatial climate signals.

Strengths

• Covers a substantial 618-year time period for climate analysis.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Data is temporally stale, last updated in 1993, with no recent revisions.
• Limited geographic scope to a single site (Cerro Baraja) in Mexico.
• Lacks metadata details on sample depth, species code PSME specifics, and measurement parameters.
