Tree Ring Chronology from Paso Cordova, Argentina (258 to -36 BP)

Tree ring width measurements from a site in Neuquén, Argentina, used for paleoclimate reconstruction. The dataset covers a 294-year period from 258 to -36 calendar years before present. It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
• Calibrate the chronology against other regional paleoclimate records using its documented time range from 258 to -36 BP.
• Analyze climate signal strength and persistence by examining the variance and autocorrelation within the ring width series.
• Study the response of native tree species to climate forcing in the Patagonian region of Argentina.

Strengths

• Covers a specific 294-year time period (258 to -36 BP) for climate analysis.
• Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology archive.
• Focuses on a single geographic location (Paso Cordova, Neuquén, Argentina) for localized study.

Limitations

• Data is temporally stale, with a last update date of 1986, potentially lacking modern reanalysis.
• The sample is from a single site, limiting spatial representativeness for broader regional conclusions.
• Specific metadata on sample depth, species, and measurement statistics are not provided in the basic description.
