Russian Tree Ring Chronology from 310 to -40 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Ozera Lama site in Russia. The chronology covers 350 years, from 310 to -40 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, last updated in 1990.

Use Cases

• Reconstruct past temperature anomalies by analyzing annual tree ring width measurements.
• Calibrate climate proxy models using the 350-year tree ring chronology from Russia.
• Study regional climate events in Eastern Europe by correlating ring density data with known historical periods.
• Validate broader hemispheric climate reconstructions by incorporating this site-specific tree ring series.

Strengths

• 350-year continuous chronology provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Specific geographic location (Russia, Eastern Europe) enables focused regional analysis.

Limitations

• Temporal coverage ends at -40 BP (roughly 1990 years ago), lacking modern instrumental overlap.
• Data is from a single site (Ozera Lama), limiting spatial representativeness for all of Russia.
• The last update was in 1990, indicating the methodology and metadata may not reflect current standards.
