Schweingruber Tree Ring Chronology for Ary-Ongorbynf River Basin

Tree ring width measurements from the Ary-Ongorbynf River B site in Russia, Eastern Europe. The chronology covers a 53-year period from 13 to -40 calendar years before present (BP). This paleoclimatology study was archived by NOAA National Centers for Environmental Information under the World Data Service.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing inter-annual variations in tree ring width measurements.
• Calibrate regional climate models using the 53-year tree ring chronology as a proxy for environmental conditions before present.
• Study ecological responses to historical climate events by examining growth patterns captured in the ring width time series.
• Cross-date and validate other tree ring chronologies from Eastern Europe using this ITRDB RUSS163 series.

Strengths

• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
• Chronology provides a continuous 53-year time series for climate proxy analysis.

Limitations

• Temporal coverage is limited to 53 years, which is short for many climate reconstruction studies.
• Geographic scope is restricted to a single site (Ary-Ongorbynf River B) in Russia.
• The dataset was last updated in 1990, indicating potential staleness in metadata or methods.
