Frias Glacier Tree Ring Chronology from Argentina

Tree ring width measurements from the Frias Glacier region in Argentina provide a proxy climate record. The chronology covers 390 years, from 355 to -35 calendar years before present. This dataset was archived by the NOAA National Centers for Environmental Information's Paleoclimatology program.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time series.
• Calibrate the chronology against other proxy records from the Andes using its 390-year temporal coverage.
• Analyze climate forcing events visible in the ring width parameter for the specified geographic location in Argentina.

Strengths

• Time series spans 390 calendar years, from 355 to -35 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date recorded as 1985-01-01.
• Specific sample size, measurement parameters, and data quality metrics are not provided in the description.
