Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate the chronology against other proxy records for the 56-year period from -44 to 11 BP.
• Analyze inter-annual climate variability in central Canada from the ring-width measurements.

Strengths

• Data spans a continuous 56-year period for climate analysis.
