Mexican Tree Ring Chronology from Las Tinajas, 329 to 43 BCE

329 to 43 BCE tree ring data from a site in Mexico, archived by NOAA's World Data Service for Paleoclimatology. The dataset provides parameters for dendrochronological analysis to reconstruct past environmental conditions. It was published by the NOAA National Centers for Environmental Information, with a last update recorded in 1993.

Use Cases

• Reconstruct annual precipitation or drought indices from tree ring width parameters for central Mexico.
• Calibrate radiocarbon dating or other chronological models using the provided calendar year BP time series.
• Analyze long-term climate trends and variability in the region over the 372-year period covered by the chronology.
• Compare this site's dendroclimatic signal with other ITRDB chronologies to study spatial climate patterns.

Strengths

• Covers a 372-year period from 329 to 43 BCE, providing a multi-century environmental record.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Part of the International Tree-Ring Data Bank (ITRDB), enabling standardized comparison with global datasets.

Limitations

• Data is temporally stale, with a last update in 1993, potentially lacking modern reanalysis or corrections.
• Specific parameters, sample depth, and measurement statistics are unknown without accessing full metadata.
• Geographic coverage is limited to a single site (Las Tinajas), which may not be representative of broader regions.
