Upper Boundary of the Biosphere

Full title: Upper Boundary of the Biosphere


Little is known about the populations inhabiting the upper reaches of Earth's atmosphere. This Topical Team will develop a strategy for determining the vertical profile of biota in our atmosphere. It will outline a program based on aerosol sampling by high-flying airplanes, balloons, sounding rockets, satellites, and the International Space Station; as well as studies in ground-based simulation facilities. This work will contribute to: 1) understand how life adapts to extreme environments; 2) better establish the distribution of life in planets and the possibility of organisms to escape their parent body; and 3) map the aerial migration of microbes around the globe, a subject of health and ecological interest.
