Nano- to micrometer sized particles and droplets in air, known as aerosols, play a decisive role in the formation of clouds, for the climate of Earth, for air quality and for human health. However, many processes have not yet been researched in detail. At the SPB/SFX instrument of European XFEL, Nønne Prisle and her team from the University of Oulu, Finland, are therefore investigating artificial aerosol mixtures and their interaction with water vapour, which is omnipresent in the atmosphere. The extraordinarily high intensity of the X-ray flashes from European XFEL and their high repetition rate allow precise small-angle X-ray scattering (SAXS) in combination with single particle imaging (SPI). The results could have far-reaching implications for the fundamental understanding of atmospheric aerosols and their impact on the global climate.
