Tree Ring Chronology from Lago Fontana, Argentina (338-Year Span)

338 years of tree ring parameters from a site in Chubut, Argentina, used for paleoclimate reconstruction. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was last updated in the system in 1985.

Use Cases

• Reconstructing past temperature or precipitation anomalies from tree ring width measurements for the Patagonian region.
• Calibrating climate proxy models using the 338-year time series covering calendar years 303 to -35 BP.
• Analyzing long-term climate trends and extreme events specific to the geographic location of Argentina.

Strengths

• Covers a 338-year time period (303 to -35 BP) for long-term trend analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last updated date of 1985, potentially lacking modern re-calibration.
• Sample size, geographic representativeness, and specific measured parameters are unknown from the provided metadata.
