Tree ring width measurements from the Kotuy River region in Russia provide a paleoclimate record. The chronology covers 109 years from 69 to -40 calendar years before present. This archived study is part of the NOAA NCEI World Data Service for Paleoclimatology and was last updated in 1990.
Use Cases
- Calibrating climate models by comparing tree ring width variations against known historical climate events.
- Reconstructing past temperature or moisture stress in Eastern Europe using the annual resolution of ring widths.
- Analyzing long-term ecological trends by examining growth patterns over the 109-year chronology.
Strengths
- 109-year chronology providing a continuous annual-resolution record.
- Data is archived and curated by NOAA NCEI, an authoritative environmental data center.
Limitations
- Temporal coverage is relatively short for paleoclimate studies at 109 years.
- Data is temporally stale, with the last recorded update in 1990.
- Geographic scope is limited to a single site in the Kotuy River region.
