NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Tannsjö site in Sweden. The data provides annual growth measurements for Pinus sylvestris (PISY) trees, covering a time period from 430 to -49 calendar years before present. This dataset was contributed to the International Tree-Ring Data Bank (ITRDB) and last updated via NOAA NCEI in 1999.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Scandinavia by analyzing annual tree-ring width variations.
- Calibrate radiocarbon dating or synchronize timelines by cross-referencing this Pinus sylvestris chronology with other regional proxy records.
- Study long-term ecological growth patterns and responses to environmental stressors from the specific tree-ring parameters.
- Validate climate model simulations for the last millennium using this high-resolution proxy data point from Sweden.
Strengths
- Covers a substantial 479-year time period (430 to -49 BP)
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology and ITRDB
Limitations
- Data recency is low, last updated in 1999, potentially missing modern methodological revisions
- Specific sample size, measurement parameters, and data granularity are unknown from the provided metadata
