Cerro Baraja Tree-Ring Width Chronology for Mexican Climate Reconstruction

480 years of tree-ring width data from Cerro Baraja, Mexico, covering the period from 450 to -30 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was last updated in the NOAA system in 1980.

Use Cases

• Reconstruct past precipitation or temperature anomalies using the tree-ring width proxy.
• Calibrate the tree-ring width chronology against instrumental climate records for the region.
• Analyze long-term climate trends and variability in central Mexico over a 480-year period.
• Compare this chronology with other regional tree-ring datasets to study spatial climate patterns.

Strengths

• Covers a 480-year time period (450 to -30 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data recency is low, with a last update recorded in 1980.
• Sample size and replication depth for the tree-ring chronology are unknown from the description.
• Geographic coverage is limited to a single site (Cerro Baraja) in Mexico.
