NOAA NCEI archives a paleoclimatology dataset containing tree ring parameters from the Bilibina and Mali Anuj River sites in Russia. The data provides a time series covering 518 to -41 calendar years before present (BP), used for climate reconstruction. This study was contributed to the International Tree-Ring Data Bank (ITRDB) and last updated in 1991.
Use Cases
- Reconstruct past temperature or precipitation anomalies for Eastern Europe using the tree-ring width chronology.
- Calibrate and validate climate model simulations for the last millennium using the dated annual resolution time series.
- Analyze long-term climate trends and extreme events in Russia from 518 to -41 BP via the standardized ring-width index.
- Cross-date and synchronize other tree-ring records from the region using the master chronology from this study.
Strengths
- Time series spans 559 years (518 to -41 BP), providing multi-century climate context.
- Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) and NOAA WDS Paleoclimatology archive.
Limitations
- Data is temporally stale, with a last update date of 1991.
- Geographic coverage is limited to two specific sites in Russia, limiting broad spatial analysis.
- Sample size and replication statistics for the tree-ring chronology are unknown.
