Concentration of atmospheric and oceanic carbon monoxide: 2012 the Arctic Ocean

Atmospheric carbon monoxide in the marine boundary layer was monitored from August 1 to September 10 by LGR along the cruise track of R/V Araon from Nome(Alaska) to Nome carrying out a series of expeditions in the Arctic Ocean. The air inlet to the instrument was located at 29 m asl and CO was measured every 10 seconds. Atmospheric carbon monoxide plays a key role in tropospheric chemistry in particular related to the oxidation capacity and to understanding the chemical processes in the marine boundary layer. Also underway continuous measurement of CO enables us to estimate marine emission of CO in global scale.
