Short summary
Atmospheric mineral dust can help clouds form ice, changing cloud properties and affecting weather and climate. We tested dust from Morocco and Iceland in more than 300 controlled laboratory experiments. Icelandic samples were up to 100 times less able to promote ice formation than Moroccan samples, and showed mineral-composition dependence. The results show the role of larger dust particles in ice nucleation and their relationship with mineralogy and size for low- and high-latitude sources.
