Gryspeerdt, Edward; Smith, Tristan; O'Keeffe, Eoin; Christensen, Matthew; Goldsworth, Fraser (2019): The impact of ship emission controls recorded by cloud properties. In Geophys. Res. Lett. DOI: 10.1029/2019GL084700.
"This work uses over 17,000 shiptracks during the implementation of fuel sulfur content regulations to demonstrate the central role of sulfate aerosol in ship exhaust for modifying clouds. By connecting individual shiptracks to transponder data, it is shown that almost half of shiptracks are likely undetected, masking a significant contribution to the climate impact of shipping. A pathway to retrieving ship sulfate emissions is demonstrated, showing how cloud observations could be used to monitor air pollution."
