When you release the hairspray or spray paint out of its can, it releases a mist of small liquid droplets, called an aerosol spray. However, the particulate matter (PM) in our atmosphere can also be referred to as an aerosol because it is suspended within the gases in the air.
Aerosol particles affect Earth's climate through processes of scattering and absorption of radiation in the atmosphere, through interaction with clouds, and by altering the albedo of snow and ice. This chapter describes how these processes affect Earth's energy balance and how changes in energy balance affect temperature and precipitation.
The meaning of AEROSOL is a suspension of fine solid or liquid particles in gas; also, aerosols plural : the fine particles of an aerosol. How to use aerosol in a sentence.
Aerosols also have complex effects on clouds and precipitation. Broadly speaking, aerosols are thought to suppress precipitation because the particles decrease the size of water droplets in clouds. However, under some environmental conditions, aerosols can lead to taller clouds that are more likely to produce lightning and strong downpours.
Summary. Atmospheric aerosols are suspensions of solid particles or liquid droplets in air, which include sulfate (SO 4 ), nitrate (NO 3 ), ammonium (NH 4 ), organic carbon (OC), black carbon (BC), dust, and sea salt. Aerosol particles exhibit vastly different sizes spanning a few orders of magnitude from 10 −3 to 10 μm.
