Altai Mountain Tree Ring Chronology from 400 to 45 BCE

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Altai Mountains in Russia. The dataset covers a 445-year period from 400 to 45 calendar years before present. It was published by NOAA's National Centers for Environmental Information in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
• Calibrate radiocarbon dating sequences by aligning the tree ring chronology with known historical periods.
• Analyze climate forcing events, such as volcanic eruptions, by identifying marker years of suppressed growth in the ring series.
• Compare climatic signals in this Russian chronology with other tree ring records from the Northern Hemisphere.

Strengths

• Covers a specific 445-year period from 400 to 45 BCE.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1995, potentially missing modern reanalysis.
• Specific sample size, measurement parameters, and site details are not provided in the metadata.
