Sea-salt aerosol (SSA) particles are ubiquitous in the marine boundary layer and over coastal areas. Therefore SSA have ability to directly and indirectly affect the Earth’s radiation balance. The influence SSA have on climate is related to their water uptake and ice nucleation characteristics. In this study, optical microscopy coupled with Raman spectroscopy was used to detect the formation of...

Portland cement was studied for its nucleating ability by the freezing behaviour exhibited of drops produced from aqueous suspension of Portland cement vis-a-vis of drops produced from suspensions of AgI, 2AgI.NaI and PbI,. I t is revealing to note that, at temperature colder than 5"C, Portland cement is as potent an ice nucleant as is either 2AgIaNaI or PbI,. At temperatures approaching 5"C, P...

The formation of ice affects many aspects of our everyday life as well as important technologies such as cryotherapy and cryopreservation. Foreign substances almost always aid water freezing through heterogeneous ice nucleation, but the molecular details of this process remain largely unknown. In fact, insight into the microscopic mechanism of ice formation on different substrates is difficult ...

The question whether or not the presence of warm hydrometeors in clouds may play a significant role nucleation new ice particles has been debated for several decades. While early works Fukuta and Lee (1986) Baker (1991) indicated that it might be irrelevant, more recent study Prabhakaran et al. (2019) [arXiv:1906.06129] suggested otherwise. In this work, we are aiming to quantify ice-nucleating...

Abstract. The incomplete understanding of aerosol–cloud interactions introduces large uncertainties when simulating the cloud radiative forcing in climate models. physical and optical properties a cloud, as well evolution precipitation, are strong functions hydrometeor phase. Aerosol particles support phase transition water atmosphere from meta-stable to thermodynamically preferred stable In tr...
