Low-troposphere microbial communities differ between dry-air and rainfall but do not show strong seasonal patterns in Metro Atlanta, Southeast USA

L. Davila-Santiago, C. Erb, L. H. Yang, J. Hall, A. Negron, I. D'amico, J. Hatt, K. T. Konstantinidis

The paper compares microbial communities in dry air and rainfall in Metro Atlanta, finding dry air has more human pathogens and allergens, but no strong seasonal patterns.
