A tree-ring chronology from the Aktasch Valley in the Altai region of Russia, providing annual climate proxy data. The dataset covers 393 calendar years, from 349 to -44 years before present, and is archived by the NOAA National Centers for Environmental Information. It was published as part of the World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
- Calibrate radiocarbon dating curves using the precisely dated tree-ring sequence.
- Study ecological responses to historical climate events by examining growth patterns in the chronology.
- Compare Central Asian climate history with other proxy records using the standardized time-series data.
Strengths
- Covers a 393-year time period from 349 to -44 BP, providing a multi-century climate record.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection, ensuring standardized formatting and metadata.
Limitations
- Data is temporally stale, with a last update recorded in 1994, potentially lacking modern reanalysis.
- Limited geographic scope to a single valley in the Altai, which may not represent broader regional climate.
