Atmospheric Particle Production from Freshwater and Oceanic Wave-breaking
Wave-breaking in natural bodies of water forms bubbles that burst at the air-sea interface to produces atmospheric particles, known as sea spray aerosol (SSA) in marine environments and lake spray aerosol (LSA) in freshwater environments. While the properties and associated health and climate impact...
