Scientists recently combined experimental approaches and molecular dynamics modeling to gain new insights into the internal structure of sea salt particles and relate it to their fundamental chemical reactivity in the atmosphere. They used laboratory-proxy sea salt composed of mixed sodium methanesulfonate and sodium chloride salts (CH3SO3Na/NaCl). Sea salt particles are emitted into the atmosphere by the action of ocean waves and bubble bursting at the ocean surface.
