Argentine Tree Ring Chronology from 262 to 31 BC

Tree ring width measurements from Argentina provide a proxy record for past climate conditions. The chronology covers a 293-year period from 262 to 31 calendar years before present. Data is archived by NOAA National Centers for Environmental Information under its Paleoclimatology program.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate the tree ring chronology against other regional paleoclimate proxies for cross-validation.
• Analyze the frequency of narrow or wide rings to identify periods of environmental stress or favorable growth conditions.

Strengths

• 293-year continuous chronology from 262 to 31 BC
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology

Limitations

• Temporal coverage is limited to a specific 293-year window in the past
• Data is from a single geographic location in Argentina, limiting spatial representativeness
• Last metadata update was in 1981, indicating potential staleness in documentation
