“…Also, the type of chemical deposits on the surface of VA particles (Casas et al., 2019; Mueller et al., 2017) could potentially influence their ice nucleation activities. For example, anhydrite (CaSO 4 ) formed on milled VA surfaces by reaction with SO 2 at high temperatures may enhance INA, potentially by creating ice‐active sites through a particular combination of surface chemistry and topography (Maters et al., 2020). Milling is expected to alter the chemical properties of VA surfaces by destroying features that have been generated by such ash‐gas/aerosol interactions in the eruption plume (e.g., Delmelle et al., 2007; Maters et al., 2016).…”

“…However, in situations where VA samples have been milled before testing (e.g., Genareau et al., 2018; Maters et al., 2019), a correlation between bulk composition and INA may be revealed, since water interacts with the newly exposed surface more closely matching the bulk composition during freezing experiments. Therefore, we conclude that bulk chemical composition does not have primary importance in the INA of natural VA, and that the surface chemical composition may exert an influence on the INA of VA. A recent study on VA INA has shown that surface chemical composition can influence INA of milled VA samples (Maters et al., 2020). There might also be synergistic effects involving a complex interplay of surface chemical composition and other physicochemical properties in determining the INA of VA–this requires further investigation.…”

Volcanic ash (VA) from explosive eruptions contributes to aerosol loadings in the atmosphere. Aside from the negative impact of VA on air quality and aviation, these particles can alter the optical and microphysical properties of clouds by triggering ice formation, thereby influencing precipitation and climate. Depending on the volcano and eruption style, VA displays a wide range of different physical, chemical, and mineralogical properties. Here, we present a unique data set on the ice nucleation activity of 15 VA samples obtained from different volcanoes worldwide. The ice nucleation activities of these samples were studied in the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) cloud simulation chamber as well as with the Ice Nucleation Spectrometer of the Karlsruhe Institute of Technology (INSEKT). All VA particles nucleated ice in the immersion freezing mode from 263 to 238K with ice nucleation active site (INAS) densities ranging from ∼105 to 1011 m−2, respectively. The variabilities observed among the VA samples, at any given temperature, range over 3.5 orders of magnitude. The ice‐nucleating abilities of VA samples correlate to varying degrees with their bulk pyroxene and plagioclase contents as a function of temperature. We combined our new data set with existing literature data to develop an improved ice nucleation parameterization for natural VA in the immersion freezing mode. This should be useful for modeling the impact of VA on clouds.

Volcanic electrification: recent advances and future perspectives

The electrification of volcanic plumes has been described intermittently since at least the time of Pliny the Younger and the 79 AD eruption of Vesuvius. Although sometimes disregarded in the past as secondary effects, recent work suggests that the electrical properties of volcanic plumes reveal intrinsic and otherwise inaccessible parameters of explosive eruptions. An increasing number of volcanic lightning studies across the last decade have shown that electrification is ubiquitous in volcanic plumes. Technological advances in engineering and numerical modelling, paired with close observation of recent eruptions and dedicated laboratory studies (shock-tube and current impulse experiments), show that charge generation and electrical activity are related to the physical, chemical, and dynamic processes underpinning the eruption itself. Refining our understanding of volcanic plume electrification will continue advancing the fundamental understanding of eruptive processes to improve volcano monitoring. Realizing this goal, however, requires an interdisciplinary approach at the intersection of volcanology, atmospheric science, atmospheric electricity, and engineering. Our paper summarizes the rapid and steady progress achieved in recent volcanic lightning research and provides a vision for future developments in this growing field.
