TL;DR: In this article, a new parameterization of immersion freezing on desert dust particles derived from a large number of experiments carried out at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) cloud chamber facility is presented.

TL;DR: The effect of OH aging is isolated, confirming the hypothesis that hydroxyl radical (OH) aging significantly increases the concentration of first-generation biogenic secondary organic aerosol (SOA), and can be described by a mechanism suitable for implementation in models.

TL;DR: In this paper, a historical perspective is provided on the methods and challenges of measuring ice nuclei, and various factors that led to a lull in research efforts during a nearly 20-yr period centered about 30 yr ago.

TL;DR: In this paper, the authors compared the performance of 17 different immersion freezing measurements with respect to surface area-based and geometric surface-site-based ns(T) spectra and showed that the immersion freezing efficiency expressed in ns of illite-rich clay mineral particles is relatively independent of droplet size, particle mass in suspension, particle size and cooling rate during freezing.

TL;DR: In this paper, a simple structural model, assuming an icosahedral core decorated by the additional atoms, accounts for these anomalies reasonably well up to n=561, in striking agreement with the number of atoms required to build 3, 4, and 5 complete coordination shells, respectively.
