Monte Grande Magallanes Tree Ring Chronology from Argentina

273 to -38 calendar years before present of tree ring parameters from Argentina, used for paleoclimate reconstruction. This archived study is a Tree Ring dataset from the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. The data was contributed by Roig and last updated in the archive in 1988.

Use Cases

• Reconstructing past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrating radiocarbon dating for the Southern Hemisphere using the dated tree ring series.
• Analyzing climate periodicity and extreme events in Patagonia from the annual-resolution time series.
• Comparing this Southern Hemisphere tree ring record with other paleoclimate proxies for hemispheric climate studies.

Strengths

• Covers a 311-year period from 273 to -38 calendar years BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology, ensuring archival stability and metadata standards.

Limitations

• The dataset is temporally stale, with a last recorded update in 1988, potentially missing newer methodological refinements.
• Specific parameters, sample depth, and measurement uncertainties are not detailed in the provided description, requiring metadata review.
