Argentine Tree Ring Chronology from 467 to 24 BC

467 to 24 BC tree ring data from Neuquen, Argentina, archived by NOAA's World Data Service for Paleoclimatology. The dataset provides parameters for dendrochronological analysis to support paleoclimate studies. This archived study was published by NOAA NCEI in 1974.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width parameters as a proxy.
• Calibrate regional climate models by comparing the tree ring chronology with other paleoclimate records for the period 467-24 BC.
• Analyze long-term climate trends in the Neuquen region of Argentina through time-series analysis of the ring data.
• Validate hemispheric climate reconstructions by incorporating this South American tree ring series into broader datasets.

Strengths

• Covers a 491-year period from 467 to 24 BC, providing a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1974, and may lack modern methodological refinements.
• Geographic coverage is limited to a single site in Neuquen, Argentina, reducing regional representativeness.
• Specific parameters, sample size, and measurement details are unknown without accessing full metadata.
