Lithuanian Tree Ring Chronology for Paleoclimate Reconstruction

146-year tree ring chronology from 97 to -49 calendar years before present, covering the period around the start of the Common Era. The dataset contains parameters from tree rings in Lithuania and is archived by NOAA's World Data Service for Paleoclimatology. This study was published as part of NOAA's Paleoclimatology collection.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Northern Europe using annual tree-ring width measurements.
• Calibrate radiocarbon dating or other chronological models for the Baltic region using the dated tree-ring series.
• Analyze the frequency of environmental stressors, such as droughts or cold periods, indicated by tree-ring parameter anomalies.
• Compare this Lithuanian chronology with other European tree-ring datasets to study spatial climate patterns over the 146-year period.

Strengths

• Covers a specific 146-year period (97 to -49 BP) critical for studying climate around the start of the Common Era.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Includes geospatial location data for Lithuania, enabling regional analysis.

Limitations

• Temporal coverage is limited to 146 years, which is short for analyzing long-term climate cycles.
• Data is geographically limited to Lithuania, which may not be representative of broader Northern European climate.
• The dataset's last known update was in 1999, indicating it is a static archive and may not reflect current data standards or include subsequent re-analyses.
