Concentration of atmospheric carbon monoxide: 2012 Arctic and Northwestern Pacific Oceans

Atmospheric carbon monoxide in the marine boundary layer was monitored from July 14 to September 24 by the LGR CO/N2O analyzer along the cruise track of R/V Araon in the Northwestern Pacific and the Arctic Ocean. The air inlet to the instrument wa located at 29 m asl and the CO was measured at 0.1 Hz. 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.
