Argentine Tree Ring Chronology from Los Laureles Salta

Tree ring width measurements from Los Laureles Salta in Argentina provide a proxy climate record. The data covers a period from 124 to -29 calendar years before present. NOAA National Centers for Environmental Information archives this paleoclimatology study.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the proxy tree ring record with instrumental data for the region.
• Analyze long-term climate trends in northwestern Argentina over the 153-year period covered by the chronology.
• Study the frequency of extreme climatic events, such as droughts, indicated by narrow tree rings.

Strengths

• Data spans a 153-year period (124 to -29 BP), providing a multi-decadal climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage ends at -29 BP, which may limit direct comparison with very recent instrumental records.
• Sample size and replication statistics for the tree ring chronology are unknown, affecting uncertainty estimates.
• Data was last updated in 1979, indicating the core record is static and may not reflect newer analytical methods.
