Finland's Rokuan National Park provides a tree-ring chronology for climate reconstruction. The dataset covers 140 calendar years, from 111 to -28 years before present, based on measurements from Scots Pine (PISY). It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1978.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
- Calibrate and validate climate models for Northern Europe using the dated annual growth records.
- Analyze growth patterns and potential climate stressors within the specified 140-year time period.
- Compare this Scots Pine (PISY) chronology with other regional datasets to identify broader climatic signals.
Strengths
- Data spans a continuous 140-year period (111 to -28 BP), providing a multi-decadal climate record.
- Sourced from a specific, documented location (Rokuan National Park, Finland) and tree species (Scots Pine).
- Archived and maintained by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short (140 years) for long-term climate trend analysis.
- Data is geographically limited to a single park in Finland, reducing regional representativeness.
- The dataset has not been updated since 1978, potentially lacking modern reanalysis or calibration.
