Argentine Tree Ring Chronology from 229 to 39 BCE

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Confluencia 2 site in Neuquen, Argentina. The dataset covers a 268-year period from 229 to 39 years before present (BP). It was contributed by researcher Villalba and archived by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation using tree ring width measurements as a proxy.
• Calibrate regional climate models by comparing the chronology with other paleoclimate records.
• Analyze climate periodicity over a 268-year span in pre-modern Patagonia.
• Study the response of AUCH tree species to historical environmental stressors.

Strengths

• Covers a specific 268-year period from 229 to 39 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a geographically specific record for Neuquen, Argentina.

Limitations

• Temporal coverage is limited to a single 268-year block, not continuous to present.
• Data last updated in 1989, potentially lacking modern reanalysis or corrections.
• Unknown sample depth and replication statistics for the tree ring series.
