Rio Horqueta Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Rio Horqueta in Tucuman, Argentina. The data provides a 254-year record of tree growth from 221 to -32 calendar years before present, used for climate reconstruction. This dataset is part of the NOAA National Centers for Environmental Information's paleoclimate collection, last updated in 1982.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Analyze the time-series for extreme climate events like droughts within the 254-year record.
• Calibrate the tree-ring chronology against other regional paleoclimate proxies from the ITRDB ARGE042 series.
• Study long-term ecological growth patterns in Argentinian forests from the dated ring measurements.

Strengths

• Covers a 254-year time period (221 to -32 BP).
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Data is temporally stale, last updated in 1982.
• Specific sample depth, measurement parameters, and geographic coordinates require metadata review.
• Limited to a single geographic location in Tucuman, Argentina.
