WebAerosols also can act as sites for chemical reactions to take place (heterogeneous chemistry). The most significant of these reactions are those that lead to the destruction of stratospheric ozone. During winter in … Aerosol is defined as a suspension system of solid or liquid particles in a gas. An aerosol includes both the particles and the suspending gas, which is usually air. Meteorologists usually refer them as particle matter - PM2.5 or PM10, depending on their size. Frederick G. Donnan presumably first used the term … See more An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog or mist, dust, forest exudates, and geyser steam. Examples of … See more People generate aerosols for various purposes, including: • as test aerosols for calibrating instruments, performing research, and testing sampling equipment and air filters; • to deliver deodorants, paints, and other consumer products in sprays; See more Aerosol can either be measured in-situ or with remote sensing techniques.
