SPIN modification for low-temperature experiments [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
The SPectrometer for Ice Nuclei (SPIN) has been modified to access ice nucleation at low temperatures. The modification consists of a reconfiguration of components from SPIN's cooling system to provide refrigerant with a low boiling point to the chamber.

Deposition freezing, pore condensation freezing and adsorption: three processes, one description? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Heterogeneous ice nucleation impacts the hydrological cycle and climate through affecting cloud microphysical state and radiative properties. Despite decades of research, a quantitative description and understanding of heterogeneous ice nucleation ...

Freezing nucleation apparatus puts new slant on study of biological ice nucleators in precipitation [PDF]

open access: yes, 2014
For decades, drop-freezing instruments have contributed to a better understanding of biological ice nucleation and its likely implications for cloud and precipitation development. Yet, current instruments have limitations.

A new temperature- and humidity-dependent surface site density approach for deposition ice nucleation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Deposition nucleation experiments with Arizona Test Dust (ATD) as a surrogate for mineral dusts were conducted at the AIDA cloud chamber at temperatures between 220 and 250 K.

How Do Size and Aggregation of Ice-binding Proteins Control their Ice Nucleation Efficiency [PDF]

open access: yes, 2018
Organisms that thrive at cold temperatures produce ice-binding proteins to manage the nucleation and growth of ice. Bacterial ice-nucleating proteins (INP) are typically large and form aggregates in the cell membrane, while insect hyperactive antifreeze ...

Ice nucleation properties of fine ash particles from the Eyjafjallajökull eruption in April 2010 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
During the eruption of the Eyjafjallajökull volcano in the south of Iceland in April/May 2010, about 40 Tg of ash mass were emitted into the atmosphere.

E Pluribus Unum: Functional Aggregation of Cell-Free Proteins Enables Fungal Ice Nucleation [PDF]

open access: yes, 2023
Biological ice nucleation plays a key role in the survival of cold-adapted organisms. Several species of bacteria, fungi, and insects produce ice nucleators (INs) that enable ice formation at temperatures above -10 oC.

Cirrus parameterisation and the role of ice nuclei. [PDF]

open access: yes, 2005
A parametrization of cirrus clouds formed by homogeneous nucleation is improved so that it can be used more easily in general-circulation models (GCMs) and climate models.

Heterogeneous ice nucleation: exploring the transition from stochastic to singular freezing behavior [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Heterogeneous ice nucleation, a primary pathway for ice formation in the atmosphere, has been described alternately as being stochastic, in direct analogy with homogeneous nucleation, or singular, with ice nuclei initiating freezing at deterministic ...

A comprehensive parameterization of heterogeneous ice nucleation of dust surrogate: laboratory study with hematite particles and its application to atmospheric models [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
A new heterogeneous ice nucleation parameterization that covers a wide temperature range (−36 to −78 °C) is presented. Developing and testing such an ice nucleation parameterization, which is constrained through identical experimental conditions, is ...
