Tree ring width measurements from the Kotuykan River region in Russia provide a 135-year climate proxy record. The NOAA National Centers for Environmental Information archives this dataset for paleoclimate research. Data coverage spans from 95 to -40 calendar years before present.
Use Cases
- Calibrate climate models using the tree ring width time-series as a proxy for historical temperature or precipitation.
- Analyze growth anomaly patterns within the chronology to identify extreme climatic events like droughts.
- Cross-date and validate other tree ring chronologies from northern Eurasia using this established series.
- Reconstruct past atmospheric circulation patterns by correlating ring width data with other regional proxy records.
Strengths
- Covers a 135-year time period for climate proxy analysis.
- Archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short for long-term climate trend analysis.
- Geographic scope is limited to a single river region in Russia.
- Data is temporally stale, last updated in 1990.
