286 calendar years of tree-ring width data from the Bystraya site in Kamchatka, Russia, extending from 286 to -41 years before present. This paleoclimatology dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service. The data was last updated in the NOAA system in 1991.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width chronology as a climate proxy.
- Calibrate radiocarbon dating or other chronological models using the dated tree-ring series from this site.
- Study the frequency of volcanic or other extreme events in Kamchatka by identifying marker years or growth suppressions in the ring-width data.
- Compare climate sensitivity of trees at this site with other ITRDB chronologies using the standardized ring-width index.
Strengths
- Covers a 327-year time period (286 to -41 BP), providing a multi-century climate record.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.
- Includes specific geographic location details for the Bystraya site in Kamchatka.
Limitations
- The dataset is temporally stale, with a last update recorded in 1991, potentially lacking modern reanalysis or corrections.
- The raw sample size, replication, and measurement uncertainty for the ring-width series are unknown from the provided metadata.
- Geographic coverage is limited to a single site, which may not be representative of broader regional climate patterns.
