Lithuanian Tree Ring Chronology for Paleoclimate Reconstruction

NOAA NCEI archives this paleoclimatology study containing tree ring parameters from Lithuania in Northern Europe. The dataset provides a time series covering 150 calendar years, from 101 to -49 years before present (BP). It was published by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology, with a last update recorded in 1999.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation using the tree ring width or density parameters as proxies.
• Calibrate regional climate models by comparing the tree ring chronology time series against known historical climate events.
• Analyze growth anomalies in the tree ring parameters to identify extreme climatic events, such as droughts or cold periods, within the 150-year span.
• Perform cross-dating with other regional tree ring chronologies using the shared time-series parameters to build a more extensive climate record.

Strengths

• Covers a specific 150-year time period (101 to -49 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 150 years, which is short for long-term climate trend analysis.
• Data is geographically restricted to Lithuania, limiting broader regional inferences.
• The dataset was last updated in 1999, indicating potential staleness in metadata or availability.
