Tree ring width measurements from pine trees (PISY) at the Ikolanniemi site in Lieksa, Finland. The chronology covers a 411-year period from 576 to 165 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
- Calibrate regional climate models using the precisely dated 411-year chronology.
- Study forest growth responses to historical environmental events recorded in the ring sequences.
- Cross-date and validate other tree ring chronologies from Northern Europe using this series.
Strengths
- 411-year continuous chronology providing a long-term environmental record.
- Precise calendar year dating for each tree ring measurement.
Limitations
- Single geographic site (Lieksa, Finland) limits regional representativeness.
- Unknown sample depth (number of trees) affects statistical confidence.
- Data ends at 165 BP, lacking modern instrumental overlap for recent calibration.
