Bryungjade River Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from the Bryungjade River region in Russia provide a 408-year climate proxy record. The dataset, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 367 to -41 calendar years before present. This study, with a last update timestamp of 1991, is part of the International Tree-Ring Data Bank collection.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree ring width series against instrumental records.
• Analyze growth response functions to identify climate drivers (e.g., summer temperature, soil moisture) limiting tree growth in this region.
• Cross-date and validate other tree ring chronologies from northeastern Russia using the established LAGM chronology.
• Study the frequency and magnitude of extreme climatic events (e.g., droughts, cold periods) recorded in the ring width indices.
• Investigate ecological changes over a 400+ year period by examining long-term trends in the standardized tree ring index series.

Strengths

• Covers a 408-year time period (367 to -41 BP), providing multi-century climate context.
• Part of the authoritative, peer-reviewed International Tree-Ring Data Bank (ITRDB) collection hosted by NOAA NCEI.
• Geographically specific to the Bryungjade river area in Russia, enabling localized climate analysis.

Limitations

• Data is temporally stale, with a last documented update in 1991, potentially lacking modern reanalysis.
• Sample size (number of tree cores) and replication depth within the chronology are unknown from the description.
• The 'calendar years before present' timescale requires careful conversion for alignment with standard historical timelines.
