TL;DR: The spectral signatures characteristic of strongly aspherical ice crystal habits in the recorded infrared extinction spectra are clearly detected and it is demonstrated that the number size distributions and total number concentrations of the ice particles that were generated in this expansion run can only be accurately derived from the recordedrared spectra when employing aspect ratios as high as 10 in the retrieval approach.

TL;DR: Overall, it is found that femtosecond laser ablation and ionization of aerosol particles is not radically different than that provided by a 193 nm excimer.

TL;DR: In this paper, the authors used an 84 m3 cloud chamber built for studies of high altitude cirrus and polar stratospheric ice clouds in the Earth's atmosphere and adapted to Martian conditions.

TL;DR: In this article, the authors investigated the nature and sources of ice nucleating particles (INPs) in mixed-phase clouds and showed the capability of combining INP concentration measurements with chemical characterization of aerosol particles using single-particle mass descriptor, source region modeling, and analysis of ice residuals.
