Concentration of atmospheric ozone: 2010 Northwestern Pacific Oceans Transect

Measuring atmospheric ozone in the marine boundary layer was monitored from July 01 to July 13 by the Thermo 49i O3 analyzer along the cruise track of R/V Araon from Incheon to Nome, Alaska, carrying out a series of expeditions in the Northwestern Pacific. The air inlet to the instrument wa located at 29 m asl and the O3 was measured at 0.017 Hz.
Tropospheric ozone (O3) is a strong greenhouse gas and it has been significantly increasing during the last century. Moreover it is an important air pollutant which adversely influence to the human health and ecosystems. Therefore our continuous shipborne measurement will help understand global radiative forcing and anthropogenic influences in the atmosphere.
