326 calendar years of tree-ring width data from the Kheta River region in Russia, extending from 326 to -40 years before present. This dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by Schweingruber. It was last updated in the repository in 1990.
Use Cases
- Reconstruct past temperature anomalies by analyzing annual tree-ring width variations.
- Calibrate climate proxy models using the dated tree-ring chronology from 326 to -40 BP.
- Study ecological resilience by examining growth response patterns in the Kheta River series.
- Compare this Siberian tree-ring record with other ITRDB chronologies to assess regional climate teleconnections.
Strengths
- Provides a 366-year continuous chronology for climate proxy analysis.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
Limitations
- Data recency is low, with a last repository update in 1990.
- Geographic coverage is limited to a single site in the Kheta River region, Russia.
- The dataset description lacks specific details on sample depth or measurement parameters.
