308 calendar years of tree ring parameters from Pinus sylvestris (PISY) in Finland, spanning from 280 to -28 years before present. This paleoclimatology study is archived by NOAA's World Data Service for Paleoclimatology. The data collection was last updated in 1978.
Use Cases
- Reconstruct past summer temperatures for Finland using the tree ring width chronology.
- Calibrate climate models by comparing the proxy temperature record from this chronology with instrumental data.
- Analyze growth anomalies in the ring width series to identify extreme climatic events like volcanic eruptions or droughts.
- Establish a dated chronology for archaeological or geological samples from the region using the provided tree ring series.
Strengths
- 308-year temporal coverage provides a multi-century climate proxy.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
- Specific geographic location (Pyhantunturi National Park, Finland) enables localized climate analysis.
Limitations
- Data is temporally stale, with a last update in 1978, potentially lacking modern re-analysis.
- Sample size and replication depth are unknown, which affects statistical confidence in the chronology.
- The time period ends at -28 BP (1978 CE), limiting analysis of recent climate change trends.
