Marine aerosols refer to tiny particles suspended in the atmosphere over the ocean. These particles can originate from a variety of sources, including sea spray, phytoplankton blooms, and human activities. Marine aerosols play a significant role in the Earth's climate system by affecting cloud formation, atmospheric chemistry, and ocean biogeochemistry. Research in this area aims to better understand the sources, composition, transport, and impacts of marine aerosols on the environment and human health. This research is important for improving climate models, predicting air quality, and informing policy decisions related to marine pollution.
