The atmosphere connects habitats across multiple spatial scales via airborne dispersal of
microbial cells, propagules and biomolecules. Atmospheric microorganisms have been …

Hygroscopicity is one of the most important physicochemical properties of aerosol particles
and also plays indispensable roles in many other scientific and technical fields. A myriad of …

Ice particle formation in tropospheric clouds significantly changes cloud radiative and
microphysical properties. Ice nucleation in the troposphere via homogeneous freezing …

Aeolian dusts serve as ice nucleating particles in mixed-phase clouds, and thereby alter the
cloud properties and lifetime. Glacial outwash plains are thought to be a major dust source …

Bacterial ice nucleators (INs) are among the most effective ice nucleators known and are
relevant for freezing processes in agriculture, the atmosphere, and the biosphere. Their …

Abstract Number concentrations of ice-nucleating particles (N INP) in the Arctic were derived
from ground-based filter samples. Examined samples had been collected in Alert (Nunavut …

The second phase of the Fifth International Ice Nucleation Workshop (FIN-02) involved the
gathering of a large number of researchers at the Karlsruhe Institute of Technology's Aerosol …

A recently designed droplet freezing assay was used to study the freezing of up to 1500
identical 0.2 nL water droplets containing suspensions of one Na/Ca-rich feldspar and three …

In many clouds, the formation of ice requires the presence of particles capable of nucleating
ice. Ice-nucleating particles (INPs) are rare in comparison to cloud condensation nuclei …

Exceedingly high levels of PM 2.5 with complex chemical composition occur frequently in
China. It has been speculated whether anthropogenic PM 2.5 may significantly contribute to …
