Contribution of pollen to atmospheric ice nuclei concentrations [PDF]
Atmospheric Chemistry and Physics, 2014 Recent studies have suggested that the ice-nucleating ability of some types of pollen is derived from non-proteinaceous macromolecules. These macromolecules may become dispersed by the rupturing of the pollen grain during wetting and drying cycles in the
