Argentine Tree Ring Chronology From El Centinela

489 to -39 calendar years before present of tree ring width measurements from Neuquen, Argentina, for paleoclimate reconstruction. This dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by R. Villalba. The data was archived by the NOAA National Centers for Environmental Information in 1989.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width parameter as a climate proxy.
• Calibrate regional climate models by comparing the time-series chronology against instrumental climate records.
• Analyze long-term climate trends in Neuquen, Argentina, by examining the variance in the ring width data over the 528-year period.
• Perform cross-dating with other Southern Hemisphere tree ring chronologies using the annual resolution of the ring width series.

Strengths

• Time series spans 528 calendar years (489 to -39 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Includes specific geographic location (Neuquen, Argentina) for spatial analysis.

Limitations

• Dataset is temporally stale, with a last updated date of 1989, potentially lacking modern revisions.
• Sample size and replication depth (number of tree cores) are unknown, which affects statistical confidence.
• The 'years before present' (BP) dating convention requires conversion for alignment with Common Era timelines.
