**Summary**: Clouds of dust kicked up in places like the Sahara can travel thousands of miles across the planet. We can see those clouds in satellite imagery, but we don’t typically know much about the composition of that dust. That’s a huge blind spot, because those unknown characteristics—such as the particles’ lightness or darkness—have an impact on what they do. The warming and cooling of the atmosphere, snow melt, ocean or rain forest fertilization, and even cloud formation can all be affected by dust cloud composition. Mapping those dust sources is the focus of the Earth Surface Mineral Dust Source Investigation, or EMIT, which will be supported by NASA’s Land Processes Distributed Active Archive Center (LP DAAC), which is located at the USGS EROS Center. On this episode of Eyes on Earth, we hear about the importance of the mission from three members of the EMIT Science Team.
