Finnish Tree Ring Chronology from 730 to 100 BP

730-year tree ring chronology from a pine forest in Finland provides a proxy record of past climate conditions. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by researcher Meriläinen. It covers the period from approximately 1220 AD to 1850 AD, based on the 'calendar years before present' reference.

Use Cases

• Reconstruct past summer temperatures by analyzing annual tree-ring width measurements.
• Calibrate climate models using the 730-year proxy record of environmental conditions.
• Study regional climate events by cross-dating this chronology with other Scandinavian tree-ring series.
• Investigate forest growth responses to historical climate anomalies documented in the ring data.

Strengths

• 730-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Single geographic location (Valkiajärvi, Finland) limits regional representativeness.
• Precise sample size, measurement methods, and potential missing years are unknown from the description.
