Schweingruber Tree Ring Chronology from Jama River, Russia

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Jama River region in Russia. The dataset provides a 206-year record of tree growth parameters, covering the period from 162 to -44 calendar years before present. It was contributed by the Schweingruber research group and last updated in 1994.

Use Cases

• Reconstruct past temperature and precipitation anomalies by analyzing annual tree-ring width variations.
• Calibrate climate proxy models using the dated chronology to validate other paleoclimate archives.
• Study ecological responses to historical climate events through patterns in the tree growth parameters.
• Establish a regional master chronology for cross-dating other tree-ring samples from Eastern Europe.

Strengths

• 206-year continuous chronology provides a multi-century climate proxy record.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
• Geographic location (Russia, Eastern Europe) is precisely specified for spatial analysis.

Limitations

• Data is temporally stale, with no updates since its last publication in 1994.
• The 206-year record is relatively short compared to millennial-length tree-ring chronologies.
• Specific parameters, measurement methods, and sample depth are not detailed in the provided metadata.
