Dendrochronology is the scientific method of dating tree rings to the exact year they were formed. Each annual growth ring encodes information about temperature, precipitation, fire events, and ecological disturbances, creating a natural archive that extends thousands of years into the past. Bristlecone pine chronologies now reach back over 10,000 years, providing an unbroken calendar for archaeology, climatology, and earth science.
These simulations let you measure ring widths as climate proxies, crossdate overlapping samples to build master chronologies, calibrate radiocarbon dates against tree-ring timescales, reconstruct past temperatures from ring-width indices, and analyze fire scar patterns to decode wildfire history — all with interactive parameter controls and real-time visualizations.
