Schweingruber Tree Ring Chronology From Khandiga River Russia

221 calendar years of tree ring width data from the Khandiga River region in Russia, extending from 221 to -41 years before present. The dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. The original study was published in 1991.

Use Cases

• Calibrating regional climate models using tree ring width as a proxy for past temperature and precipitation.
• Analyzing the relationship between tree ring width chronology and known volcanic or climatic events within the 221-year period.
• Reconstructing historical climate conditions for Eastern Europe based on the PCOB (Presence of Cross-dated Bands) and ITRDB (International Tree Ring Data Bank) standardized parameters.

Strengths

• Covers a 262-year time period (221 to -41 BP), providing a multi-century climate proxy.
• Archived within the authoritative NOAA/NCEI World Data Service for Paleoclimatology with standardized ITRDB formatting.

Limitations

• Data is temporally stale, with the last recorded update in 1991.
• Geographic scope is limited to a single river region in Russia, limiting broader regional analysis.
• Specific sample size, measurement parameters, and potential measurement noise are not detailed in the provided metadata.
