Summertime measurements of selected nonmethane hydrocarbons in the Arctic and Subarctic during the 1988 Arctic Boundary Layer Expedition (ABLE 3A)
The concentration distributions of several nonmethane hydrocarbons (NMHIC) in the Arctic and Subarctic regions of Alaska are discussed using data obtained during July and August of 1988 as part of the Arctic Boundary Layer Expedition (ABLE 3A). Plume enhancement of some or all of the measured NMHIC...
