Altai Mountain Tree Ring Chronology from Ceminsky Pass

339 to -44 calendar years before present of tree ring width measurements from the Ceminsky Pass in the Altai Mountains, Russia. This paleoclimatology dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data collection was last updated in the NOAA system in 1994.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series as a climate proxy.
• Calibrate the chronology against known volcanic or climatic events within the 339 to -44 BP time range.
• Analyze growth trends and extreme years (narrow or wide rings) to infer past environmental stress events.
• Compare this Altai Mountains chronology (ITRDB RUSS129) with other regional tree ring datasets for spatial climate pattern analysis.

Strengths

• Covers a 383-year time period from 339 to -44 calendar years before present.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• Data collection was last updated in 1994, indicating potential staleness in metadata or availability.
• Specific sample size, measurement parameters, and geographic coordinates are not provided in the basic description.
