Tree ring width measurements from Finland provide a climate proxy record spanning 118 years. The dataset, archived by NOAA's World Data Service for Paleoclimatology, was published in 1978. It represents a foundational dendrochronological study for Scandinavia.
Use Cases
- Calibrating climate models by correlating tree ring width variations with temperature and precipitation proxies.
- Establishing a dated chronology for archaeological sites in Finland using the tree ring sequence.
- Analyzing growth anomaly years within the 118-year series to identify volcanic or climatic events.
- Comparing this Finnish tree ring series with other boreal chronologies to study regional climate patterns.
Strengths
- Temporal coverage spans 118 specific years (90 to -28 BP), providing a discrete historical window.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last update recorded in 1978, potentially missing modern reanalysis.
- Sample size and replication statistics are unknown, limiting assessment of statistical robustness.
- Geographic coverage is limited to a single location in Finland, reducing broad regional applicability.
