Tree ring width measurements from the Shaguchan River region in Russia provide a 303-year paleoclimate record from 262 to -41 calendar years before present. This dendrochronological dataset is archived by the NOAA National Centers for Environmental Information World Data Service for Paleoclimatology. The data collection was last updated in 1991.
Use Cases
- Calibrating tree ring width variations against instrumental climate records to reconstruct past temperature or precipitation.
- Analyzing the chronology for marker years (extremely narrow or wide rings) to identify volcanic eruptions or severe drought events.
- Cross-dating this Russian chronology with other Eurasian tree ring series to validate regional climate signals.
- Using the year-by-year ring width data as a proxy input for hemispheric climate model simulations.
Strengths
- Covers a 303-year time period (262 to -41 BP), providing a multi-century climate record.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- The temporal coverage ends at 41 BP (1991 CE), with no updates since the last metadata revision in 1991.
- The specific sample depth (number of trees/cores) and measurement statistics are unknown from the provided metadata.
