Marine aerosols are tiny particles or droplets that are suspended in the atmosphere above oceans and seas. They can originate from various sources, including sea spray, organic matter, and gases released by marine organisms. These aerosols play a crucial role in the Earth's climate by influencing cloud formation and affecting the amount of sunlight that reaches the surface. These particles can also impact air quality and human health when they are transported over long distances. Marine aerosols contribute to the global carbon cycle and can affect weather patterns, making them an important area of study in climate science and environmental research.
