Natural surface active agents contribute to cloud formation

Natural surface active agents contribute to cloud formation

The Finnish Meteorological Institute has taken part in an international study the purpose of which was to determine how surface-active agents occurring in nature impact the ability of small particles to form cloud droplets. This has an effect on the properties of clouds and, ultimately, on climate.
