Finnish Pine Tree Ring Chronology from 806 to 245 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from subfossil pine (PISY) samples collected at Alakieluu Louhi, Kerimäki, Finland. The chronology covers 562 years, from 806 to 245 calendar years before present. Data are maintained by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree-ring width series.
• Calibrate radiocarbon dates by cross-referencing the absolute tree-ring chronology with other proxy records.
• Analyze growth patterns and environmental stress events recorded in the Pinus sylvestris (PISY) ring sequences.
• Study regional climate dynamics in Finland and Scandinavia over a 562-year period before present.

Strengths

• Chronology spans 562 consecutive years (806 to 245 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Sample size and replication depth for individual years are unknown, which affects statistical confidence.
• Geographic coverage is limited to a single site (Alakieluu Louhi, Kerimäki) in Finland.
