Finnish Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring dataset from Finland, Scandinavia. The data covers a time period from 132 to -28 calendar years before present (BP), representing a 160-year chronology. This archived study is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstructing past temperature or precipitation in Finland using tree ring width measurements.
• Calibrating regional climate models by comparing the tree ring chronology with known historical climate events.
• Analyzing growth anomalies within the 160-year chronology to identify periods of environmental stress.
• Correlating the Finnish tree ring series with other regional proxy records for hemispheric climate analysis.

Strengths

• Data spans a continuous 160-year chronology (132 to -28 BP).
• Curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last update recorded in 1978.
• The specific sample size (number of tree cores or sites) is unknown.
• Geographic coverage is limited to a single country (Finland).
