Diurnal Air Quality Variation: How Pollutants Disperse Throughout the Day #3256357 (License: Personal Use)

This infographic illustrates diurnal atmospheric dynamics, with colored dots representing airborne pollutants dispersing across layered air masses above a city nestled between mountains. During the morning, pollutants remain concentrated near the surface due to stable inversion layers; by midday, solar heating drives vertical mixing, spreading particles upward; in the late afternoon, cooling begins to stabilize the boundary layer again. The sun’s position and cloud cover are shown to contextualize thermal effects on dispersion.

Used in environmental science articles, public health advisories, or climate education pages to explain how time of day affects air quality and pollution exposure-especially for urban planners, researchers, and concerned citizens seeking actionable insights.
