Copahue Tree Ring Chronology From Neuquen, Argentina

NOAA/WDS Paleoclimatology provides a tree-ring chronology from the Copahue region in Neuquen, Argentina. The data covers the period from 310 to -24 calendar years before present (BP), representing over three centuries of paleoclimate records. This archived study is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate models by comparing the tree-ring proxy data with instrumental records for the region.
• Analyze climate periodicity and extreme events over the 334-year span covered by the chronology.
• Study the response of Andean tree species to past climate forcings recorded in the ring parameters.

Strengths

• Data spans 334 years (from 310 to -24 BP), providing a multi-century climate record.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Temporal coverage ends at -24 BP (approximately 1974 CE), lacking recent decades.
• Geographic scope is limited to a single location (Neuquen, Argentina), reducing regional generalizability.
• Specific parameters, sample depth, and measurement details are not provided in the basic description.
