Cerro Potosi Tree Ring Chronology from 105 to -45 BP

105 to -45 calendar years before present (BP) of tree ring data from Cerro Potosi, Mexico, for paleoclimatic study. The dataset is archived by the NOAA National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology. It was published as part of the International Tree-Ring Data Bank (ITRDB) and last updated in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
• Calibrate climate models by comparing modeled past climate with the annually-resolved tree ring record.
• Analyze long-term climate trends and extreme events in central Mexico from the 105 to -45 BP time series.
• Cross-date and validate other paleoclimate archives from the region using the established tree ring chronology.

Strengths

• Time series spans 150 calendar years (105 to -45 BP), providing a multi-century climate record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) and curated by NOAA NCEI.

Limitations

• Data is temporally stale, with a last update recorded in 1995, potentially lacking modern revisions.
• Specific sample depth, replication statistics, and measurement parameters are not detailed in the provided metadata.
