The latest study published in the journal Proceedings of the National Academy of Sciences is the first to document the presence of microorganisms in the middle and upper troposphere.
Large amounts of bacteria found four to six miles above the Earth's surface interest the atmospheric scientists, as these microorganisms could play an influential role in the formation of clouds and may also have the potential to alter weather and climatic conditions. The bacteria traversing such great distances could be used for disease transmission models.
