Airborne aerosols have been thought to cause most infections, although which means of transmission is most important is not absolutely clear.

Hair particles, epidermal flakes ... airborne aerosol of fatty acids.

The airborne aerosol package includes the similar instruments for determining aerosol optical properties as at the regional surface sites.

Start of Airborne Aerosol Observatory in-situ aerosol profiles over Bondville IL.

These instruments constitute a comprehensive airborne aerosol measurement platform capable of determining a wide suite of aerosol chemical, optical and microphysical properties.

End of operations of Airborne Aerosol Observatory - This project resulted in more than 400 in-situ aerosol profiles over the Bondville site in central Illinois.

NOAA Airborne Aerosol Observatory (AAO) to commence operations based near Bondville, IL.

The microbes do not sediment in microgravity which results in persisting airborne aerosols and high microbial densities in cabin air in particular if the cabin air filtering systems are not well maintained.

Other climatologists argue that industrial processes also exert a cooling effect by depleting the stratospheric ozone layer and emitting airborne aerosols that relect sunlight,and that this partly masks the larger warming effect.
