Southern Andes Tree Ring Width Composite for Paleoclimate Reconstruction

NOAA's World Data Service for Paleoclimatology provides a composite tree-ring width dataset for the Southern Andes region in Argentina. The data covers a period from 105 to -46 calendar years before present, compiled under the PAGES LOTRED-SA project. This archived study is maintained by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct historical temperature or precipitation anomalies in the Southern Andes using the tree-ring width chronology.
• Calibrate climate proxy models by correlating the tree-ring width time series with instrumental climate records.
• Analyze long-term climate trends and variability over a 151-year period using the dated ring-width data.
• Study the response of Andean tree species to past climatic events recorded in the ring-width parameter.

Strengths

• Data spans a continuous 151-year period (105 to -46 BP).
• Part of the standardized PAGES LOTRED-SA regional reconstruction effort.
• Archived and maintained by the authoritative NOAA NCEI World Data Service.

Limitations

• Temporal coverage is relatively short for some paleoclimate studies at 151 years.
• Geographic scope is limited to specific sites in Argentina within the Southern Andes.
• Data is archived and last updated in 1996, indicating no recent revisions.
