Data sets

Data of ice nucleation measurements of aerosol samples collected during the INUIT 2016 campaign . Kai Tang https://doi.org/10.17617/3.6r

Metagenomic analysis of the atmospheric microbial composition over Cyprus P. Yordanova https://www.ebi.ac.uk/metagenomics/

Short summary

Metagenomic sequencing and freezing experiments of aerosol samples collected on Cyprus revealed rain-related short-term changes of bioaerosol and ice nuclei composition. Filtration experiments showed a rain-related enhancement of biological ice nuclei > 5 µm and < 0.1 µm. The observed effects of rainfall on the composition of atmospheric bioaerosols and ice nuclei may influence the hydrological cycle as well as the health effects of air particulate matter (pathogens, allergens).
