Argentine Tree Ring Chronology from 303 to -36 Years BP

Tree ring width chronology data from a site in Argentina, used for paleoclimate reconstruction. The time period coverage spans from 303 to -36 calendar years before present. This archived study is provided by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology and was last updated in 1986.

Use Cases

• Reconstructing past temperature or precipitation anomalies by analyzing the tree ring width chronology.
• Calibrating climate models for the Southern Hemisphere using the dated proxy record from Argentina.
• Studying climate variability and extreme events during the period covered by the chronology, from 303 to -36 BP.

Strengths

• Time series spans 339 years (from 303 to -36 BP), providing a multi-century climate record.
• Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1986, potentially missing newer methodological refinements.
• Specific sample depth, replication statistics, and measurement uncertainty for the tree ring chronology are not detailed in the provided metadata.
