Argentine Tree Ring Chronology from Cerro del Guanaco

Tree ring width data from Cerro del Guanaco in Neuquen, Argentina, provides a climate proxy record covering 494 calendar years. The dataset was archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. This paleoclimate study was last updated in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate regional climate models using the 494-year proxy record from the Andes region.
• Study climate extremes and their frequency by identifying marker years of exceptionally narrow or wide rings in the chronology.
• Compare this Southern Hemisphere tree ring series with other global paleoclimate proxies for hemispheric synchronization studies.

Strengths

• Covers a substantial 494-year time period from 453 to -41 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data recency is low, with a last update in 1991, potentially missing modern reanalysis.
• Geographic coverage is limited to a single site (Cerro del Guanaco) in Argentina.
