Aerosol science is the study of tiny particles or droplets suspended in the air, known as aerosols. These can include dust, smoke, pollen, and liquid droplets from sources like ocean waves or industrial processes. Understanding aerosols is important because they can affect air quality, climate, and human health. Researchers in aerosol science analyze how these particles are formed, how they behave in the atmosphere, and their impact on weather patterns and global warming. By studying aerosols, scientists can develop better models to predict environmental changes and inform public health policies related to air pollution.
