Atmospheric sampling site with tower at Tudor Hill, Bermuda

An atmospheric aerosol is an airborne particle made up of liquid and/or solids ranging in size from a few nanometers to a few hundred micrometers in diameter. Our motivation to study these aerosols is threefold. First, aerosols are important geochemically. Tremendous quantities of geochemically important species are transported through the environment via the atmosphere. Also, aerosols can react with gas phase species in heterogeneous chemical reactions.
