When most people think of aerosols they think of spray cans.
Coverage by the media in the 1980s and 1990s of aerosols damaging the ozone layer drove this thinking. However, it is just one type of aerosol or “atmospheric particulate”, cholorofluorocarbons (CFCs), that was causing this damage.
Countries are now phasing out the use of CFCs in line with international protocols.
Aerosols are actually just small particles found in the air that can be produced when we burn different types of fossil fuels.
Studying aerosols could help us better understand the Earth’s changing climate.
