Cerro Diego de León Tree Ring Chronology from Rio Negro, Argentina

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Cerro Diego de León site in Rio Negro, Argentina. The dataset provides paleoclimate proxy data covering a period from 404 to -41 calendar years before present. It was published by NOAA National Centers for Environmental Information and last updated in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a climate proxy.
• Analyze climate variability over a 445-year period by examining the annual resolution time-series data.
• Calibrate regional climate models by comparing the tree ring proxy record from Rio Negro, Argentina with instrumental data.
• Study the response of tree growth to past climatic events documented in the chronology.

Strengths

• Time series spans 445 calendar years (404 to -41 BP).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Data is temporally stale, last updated in 1991.
• Specific sample depth, measurement parameters, and potential uncertainties are not detailed in the provided metadata.
