540 calendar years of tree ring width data from the Olenjok River region in Russia, used for paleoclimate reconstruction. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the International Tree-Ring Data Bank. It was last updated in the repository in 1990.
Use Cases
- Reconstruct past temperature and precipitation anomalies by analyzing the annual tree ring width series.
- Calibrate radiocarbon dating and establish calendar year timelines using the dated tree ring chronology.
- Study ecological responses to historical climate events in the Siberian Arctic via the growth record.
- Compare this chronology with other ITRDB series to analyze spatial climate patterns across Northern Eurasia.
Strengths
- Covers a 540-year time series from 500 to -40 calendar years BP.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
Limitations
- The data is temporally stale, with a last repository update recorded in 1990.
- Specific measurement parameters, sample depth, and raw measurement columns are not detailed in the provided metadata.
- Geographic coverage is limited to a single site in the Olenjok River region, Russia.
