AbstractIce particle formation in tropospheric clouds significantly changes cloud radiative and microphysical properties. Ice nucleation in the troposphere via homogeneous freezing occurs at temperatures lower than −38°C and relative humidity with respect to ice above 140%. In the absence of these conditions, ice formation can proceed via heterogeneous nucleation aided by aerosol particles known as ice nucleating particles (INPs). In this chapter, new developments in identifying the heterogeneous freezing mechanisms, atmospheric relevance, uncertainties, and unknowns about INPs are described. The change in conventional wisdom regarding the requirements of INPs as new studies discover physical and chemical properties of these particles is explained. INP sources and known reasons for their ice nucleating properties are presented. The need for more studies to systematically identify particle properties that facilitate ice nucleation is highlighted. The atmospheric relevance of long-range transport, aerosol a...

- Bounding Global Aerosol Radiative Forcing of Climate Change (2020, background): “…as an INP depends on its physical characteristics and mixing state, with parti-1311 cles containing macropores being observed to nucleate ice at cirrus temperatures (Mahrt1312 et al., 2018), but there is increasing evidence that it is a poor INP at warmer temper-1313 atures (Kanji et al., 2017).”
- Opinion: Cloud-phase climate feedback and the importance of ice-nucleating particles (2020, background): “There are many aerosol particle types that possess the capability to nucleate ice, from mineral dusts to biological particles and combustion aerosol to fertile soil dusts (see the reviews of Kanji et al., 2017, Murray et al., 2012, and Hoose and Möhler, 2012).”
- Aerosol Mixing State: Measurements, Modeling, and Impacts (2019, background): “The propensity to form ice at elevated temperatures relative to homogeneous freezing is usually reported for different particle types and subpopulations of those types (e.g., different types of mineral dust, soot, or biological particles; Kanji et al., 2017).”
