Tree ring data from Lithuania provides a 171-year climate proxy record for Northern Europe. The NOAA National Centers for Environmental Information archives this paleoclimatology study under its World Data Service. The dataset was last updated in the NOAA system in 1971.
Use Cases
- Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
- Calibrate regional climate models by comparing this chronology with other proxy records from the same time period.
- Analyze growth patterns to identify extreme historical events like droughts or volcanic eruptions affecting the Gelvonai site.
Strengths
- Covers a specific 171-year period (150 to 21 BCE) for focused temporal analysis.
- Geographically precise data from a single location in Lithuania, Northern Europe.
Limitations
- The temporal coverage is relatively short for long-term climate trend analysis.
- Data from a single site may not be representative of broader regional conditions.
- The last recorded update in the source system was in 1971, indicating potential staleness.
