Romanian Tree Ring Chronology from 146 to -31 BP

Tree ring width measurements from Romania provide a climate proxy record spanning 177 years, from 146 to -31 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific study was last updated in 1981.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Eastern Europe using tree ring width as a proxy.
• Calibrate regional climate models by comparing the tree ring chronology against known historical climate periods.
• Analyze the frequency of extreme growth years (narrow or wide rings) to identify past drought or favorable climate events.
• Cross-date and validate other paleoclimate archives from the Balkan region using this established tree ring chronology.

Strengths

• Covers a continuous 177-year period from 146 to -31 BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology, ensuring archival stability.

Limitations

• The dataset has not been updated since 1981, potentially missing modern reanalysis or calibration.
• Specific sample size, measurement methods, and site details are unknown without accessing full metadata.
