Abstract:
Commercial shipping is considered as an important source of air pollution and Cloud Condensation Nuclei (CCN). To assess the climatic and environmental impacts of shipping, we performed this airborne measurement study in the region of Western European in 2019 prior to new IMO 2020 sulfur emission becoming enacted. Large numbers of ships from both Sulfur Emission Control Area (SECA) in the English Channel and the Open Sea (OS) are measured and compared. Comparison between the two regions allows us to assess how the new IMO 2020 regulation will influence the regional aerosol emissions and regional climate forcing. As the new regulation has been in effect since 1st January 2020, this study is likely to be the last direct measurement of ship plumes under the previous 3.5% FSC regime. The ship emission results presented here will also inform the furture emission inventories, policymaking, and human health studies.
