A study of the vertical scale of halogen chemistry in the Arctic troposphere during Polar Sunrise at Barrow, Alaska
International audience The vertical extent and impact of halogen chemistry in the Arctic springtime was investigated through balloon-based measurement of several atmospheric chemical components. Various chemical species, including volatile organic compounds (VOCs), ozone, and elemental mercury, that...
