Argentine Tree Ring Chronology from Rio Futaleufu

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Rio Futaleufu site in Argentina. The data provides parameters for dendrochronological analysis, covering a time period from 108 to -24 calendar years before present. This study was contributed by Lamarche and is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width parameter as a climate proxy.
• Calibrate climate models by comparing the tree-ring chronology data against instrumental records for the region.
• Analyze long-term ecological trends and forest growth patterns from the dated tree-ring sequences.
• Study extreme climate events recorded in the tree-ring parameters over the 132-year temporal coverage.

Strengths

• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.
• Provides a clearly defined temporal coverage of 132 calendar years (from 108 to -24 BP).
• Includes specific geographic location information for the study site in Argentina.

Limitations

• The dataset's last recorded update was in 1974, indicating potentially outdated metadata or collection methods.
• Specific data parameters, sample size (row count), and measurement details are unknown without accessing full metadata.
• Geographic coverage is limited to a single site (Rio Futaleufu), reducing regional representativeness.
