These data were used in a paper accepted in Ecological Monographs on 17 September 2019, entitled "Spatiotemporal patterns of microbial composition and diversity in precipitation", hereafter Aho et al. (in press). Microbes in the atmosphere have broad ecological impacts, including the potential to trigger precipitation through species and strains that act as ice nucleation particles. To characterize spatiotemporal trends of microbial assemblages in
precipitation we sequenced 16S (bacterial) and 18S (fungal) rRNA gene amplicon libraries collected from 72 precipitation events in three US states
(Idaho, Louisiana, and Virginia) over four seasons.

The datasets provided here include:
1) Read totals for fungal and bacterial operational taxonomic units (OTUs),
2) Taxonomic assignments at levels of domain through menus for individual OTUs,
3) Relevant metadata.
