<!--!introduction!--> The sources and nature of emissions of ice nucleating particles (INPs) to the atmosphere affect aerosol-cloud interactions, precipitation, and climate (via cloud phase and lifetime influences). There is a need to characterize INP emissions, categorized in some manner to define the most important classes over different regions. While past research has emphasized the global relevance of mineral dusts and other inorganic particles as atmospheric INPs, for a variety of good reasons, we highlight measurements identifying the most abundant and important classes of INPs in many mid-continental regions as emanating from organic and biological sources. INPs whose actions are dominated by unresolved biological and organic materials are features not only of emissions from non-desert continental soils, but also marine emissions (via sea spray), from biomass burning, and in the Arctic over large portions of the year. While some of these known INP sources are less efficient on a number or ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
