Schweingruber Tree Ring Chronology from Balshoia Anui Russia

Tree ring width measurements from the Balshoia Anui site in Russia provide a 499-year climate proxy record from 458 to -41 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology was last updated in the NOAA system in 1991.

Use Cases

• Reconstruct past temperature and precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate and validate climate models for Eastern Europe using a 499-year proxy record.
• Perform cross-dating with other regional tree ring chronologies to verify historical climate events.
• Study the response of boreal forest growth to climatic forcing over five centuries.

Strengths

• 499-year continuous temporal coverage from 458 to -41 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1991, indicating potential staleness in metadata or availability.
• Specific sample size, measurement methods, and replication statistics are unknown from the provided description.
• Geographic coverage is limited to a single site (Balshoia Anui) in Russia.
