Research Spotlight: New interpretation of atmospheric bromine during Arctic spring

Bromine, which destroys ozone, is emitted into the atmosphere during the Arctic spring from inorganic sources including seasalt aerosol, frost flowers, and cracks in sea ice. It had been believed that all areas of enhanced atmospheric bromine observed from space at high latitude during spring originated from these sources at Earth's surface. However, a new analysis by Salawitch et al. suggests that previous satellite measurements may have been misinterpreted.
