title: 16S rRNA gene amplicon sequencing of atmospheric precipitation: May to August samples
design: Genomic DNA was extracted from precipitation samples using the DNeasy PowerSoil Pro Kit. The V3-V4 region of the bacterial 16S rRNA gene was amplified with primers 338F/806R. Amplicons were indexed, purified, and pooled for paired-end sequencing (2x250 bp) on an Illumina NovaSeq 6014 platform.
