NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from the Olenok River region in Russia. The data provides a 190-year chronology for paleoclimate analysis, covering the period from 150 to -40 calendar years before present. The dataset was published by NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Siberia using the tree ring width chronology.
- Calibrate climate models by comparing the proxy tree ring record from 150 to -40 BP with other paleoclimate archives.
- Analyze growth response and climate sensitivity of trees in the Olenok River region over a 190-year period.
- Study frequency and magnitude of past climatic events in Eastern Europe/Russia through ring width variations.
Strengths
- 190-year continuous chronology from 150 to -40 BP provides a substantial temporal record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last recorded update in 1990.
- Specific sample size, replication statistics, and measurement parameters are unknown from the provided metadata.
- Geographic coverage is limited to a single site (Olenok River, Russia).
