Vincent Enders and colleagues from the Atmospheric Physics group and international partners deployed spectrometers on a Japanese ship that commutes along Japan’s southern coast. The sun-viewing spectrometers measured the greenhouse gases CO2 and CH4 together with CO and NO2. Examining the concentration ratios, we were able to attribute and characterize upwind emission sources in the Nagoya bay region. The study recommends our ship-borne instrument for routine usage on commuter ships in the vicinity of coastal population centers to monitor their emissions.
