Short summary
A unique environmental electron microscope was used for monitoring the evaporation of salty frost flowers. We observe a cohesive villous brine surface layer facilitating the formation of NaCl microcrystals at temperatures below −10°C as the brine oversaturation is achieved. This finding confirms the increased surface area and thus also the enhanced heterogeneous reactivity; however, no support for the easiness of fragmentation to produce aerosols can be provided.
