Some types of biological aerosol particles such as bacteria, fungal spores and pollen are known to be potent ice nuclei that form ice in the atmosphere at relatively warm temperatures. However, which…

A Contrasting Case Study of the Proportion and Types of Biological Ice Nucleating Particles from Continental and Maritime Sources

Lead Institution

Colorado State University

Principal Investigator

Paul Demott

Project type

Large-Scale EMSL Research

Biological particles may be an important source of ice nucleating particles (INPs) at modestly supercooled cloud temperatures. These particles can thus have large effects on precipitation and climate…
