Finnish Tree Ring Chronology from 466 to 262 BP

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Sodankylä Church site in Finland. The data covers a 205-year period from 466 to 262 calendar years before present. It was contributed by Meriläinen and is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing the tree-ring width parameter.
• Calibrate radiocarbon dating or other chronological models using the precisely dated tree-ring series from 466-262 BP.
• Study long-term forest growth patterns and ecological responses in Finnish Lapland using the tree-ring data.
• Validate regional climate model simulations for the past by comparing against proxy evidence from the ITRDB FINL048 record.

Strengths

• Data spans a continuous 205-year period, providing a multi-century environmental record.
• Part of the International Tree-Ring Data Bank (ITRDB), indicating standardized formatting and peer-reviewed provenance.
• Associated with a specific geographic location (Sodankylä, Finland) enabling localized analysis.

Limitations

• Temporal coverage is limited to a specific 205-year window in the distant past, with no modern or continuous record.
• The sample size (number of tree cores analyzed) and replication statistics are unknown from the provided metadata.
• Data is from a single site (FINL048), limiting spatial representativeness for broader regional conclusions.
