This study explores the role of snowpack in polar boundary layer chemistry, especially as a direct source of reactive bromine ( BrO x = BrO + Br ) and nitrogen ( NO x = NO + NO 2 ) in the Arctic springtime. Surface snow samples were collected daily from a Canadian high Arctic location at Eureka, Nun...
