Compiled information on formation of new fine particles in the atmosphere

Compiled information on formation of new fine particles in the atmosphere

A summary study indicated that the formation of fine particles varies greatly depending on the environment and human activity.

Fine particles forming in the atmosphere have a cooling effect on the climate if they grow to the size of about 100 nanometres. With respect to the impact on climate by newly formed fine particles it is significant how fast they grow: particles that grow fast have a greater likelihood to reach a size with a climatic significance than those that grow slowly.
