Lagrangian dispersion model

A Lagrangian dispersion model is a scientific tool used to predict how pollutants, like smoke or chemicals, spread in the atmosphere over time. It tracks small parcels of air as they move, mixing, and dispersing due to wind, turbulence, and other atmospheric factors. Think of it like following tiny balloons floating through the air, seeing where they go and how they spread out. This approach helps scientists estimate pollution levels in different areas, aiding in environmental management and health risk assessment by accurately modeling how contaminants disperse in the atmosphere.
