Short summary
This study looks at how natural compounds when mixed with salts in the air affect how clouds form. These compounds come from plants and are found all over the world. They are sticky, and this changes how water droplets and clouds form. Sometimes the compound spreads more easily when mixed with salt, while the other compound does not change. Depending on the condition, these mixtures can behave differently, which affects how we predict cloud formation.
