This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will establish a distributed network of meteor radars and optical instruments in the mid-latitudes of South America. The $187,713 award to Sri International, a non-profit research institute, will provide continuous measurements of upper atmospheric winds and nighttime wave perturbations in the mesosphere and thermosphere. The network will enable multi-point observations to resolve detailed four-dimensional structures of small-scale waves, which are key drivers of variability in this region. The project will also provide research opportunities for a postdoctoral researcher and PhD students, and promote international scientific collaboration with partners in the U.S., Germany, Chile, and Argentina. This award builds upon previous NSF-funded projects to leverage existing infrastructure and expertise in ground-based geospace observations.
