Review Of Recent Developments And Shortcomings In The Characterization Of Potential Atmospheric Ice Nuclei : Focus On The Tropics.
(2015-09-21)
In this paper, we summarize the four main ice nucleating aerosol types: mineral dusts,
bioaerosols, soot, and glassy organics, with the aim of demonstrating the limitations in scientifi c
literature regarding their ice ...
The role of natural mineral particles collected at one site in Patagonia as immersion freezing ice nuclei
(Elsevier Science Inc, 2018-05-15)
This work studies the role of mineral particles collected in the region of Patagonia (Neuquén, Argentina) as ice nuclei particles (INPs) by immersion freezing mode. The particle immersion-freezing ability was analyzed under ...
Pore condensation and freezing is responsible for ice formation below water saturation for porous particles
(National Academy of Sciences, 2019-04)
Ice nucleation in the atmosphere influences cloud properties, altering precipitation and the radiative balance, ultimately regulating Earth’s climate. An accepted ice nucleation pathway, known as deposition nucleation, ...
Dust archives within polar ice cores
(Elsevier, 2024)
Mineral dust aerosols are pivotal components of Earth's atmosphere and significantly influence the climate system. Investigating their impacts through ice core records offers unique insights into paleoclimate dynamics. ...
Frozen-droplets aggregation at temperature below -40°C
(Blackwell Publishing Ltd, 2018-01-05)
The onset of the aggregation process of frozen droplets was investigated in laboratory settings. The experiments were conducted in a cloud chamber controlled at temperatures cooler than −40°C, where pure water droplets ...
Solid particles in the tropical lowest stratosphere
(2007-02-22)
We report in situ and remote observations proving occasional occurrence of solid particles in the tropical lowest stratosphere, 200km from deep convective events. The particles were found during field campaigns in Southeast ...

Influence of the ambient humidity on the concentration of natural deposition-mode ice-nucleating particles
(Copernicus Publications, 2016-01)
This study reports measurements of deposition-mode ice-nucleating particle (INP) concentrations at ground level during the period July-December 2014 in Córdoba, Argentina. Ambient air was sampled into a cloud chamber where ...
The growth of ice particles in a mixed phase environment based on laboratory observations
(Elsevier Science Inc, 2014-06)
This paper describes new laboratory observations about the size evolution of ice crystals and cloud droplets immersed in a mixed-phase cloud. The experiments were performed by using a cloud chamber facility for three ...
Relative roles of biogenic emissions and Saharan dust as ice nuclei in the Amazon basin
(NATURE PUBLISHING GROUP, 2009)
Some aerosol particles, known as ice nuclei, can initiate ice formation in clouds, thereby influencing precipitation, cloud dynamics and the amount of incoming and outgoing solar radiation. In the absence of biomass burning, ...
