A survey of the ice nucleation properties of 17 different species of fungal spores
Abstract
The role of biological particles in atmospheric ice nucleation remains poorly understood. The immersion freezing properties of 17 different species of fungal spores were studied using a temperature and humidity controlled flow cell. All the spores studied were better ice nuclei when compared to the homogeneous freezing results of pure water droplets. The freezing temperatures differed between species as well, suggesting a variability in the freezing properties of fungal spores. The surface properties of the spores are discussed to better understand this spread in ice nucleation results for the fungal spores studied.
