Global Mineral Dust Source Regions to Be Measured by EMIT

From its vantage point aboard the International Space Station (ISS), NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission will map the world's mineral-dust sources, gathering information about particle color and composition as the instrument, designed at NASA's Jet Propulsion Laboratory in Southern California, orbits over the planet's dry, sparsely vegetated regions. EMIT will collect measurements of 10 important surface minerals – hematite, goethite, illite, vermiculite, calcite, dolomite, montmorillonite, kaolinite, chlorite, and gypsum – in arid regions between 50-degree south and north latitudes in Africa, Asia, North and South America, and Australia. The data EMIT collects will help scientists better understand the role of airborne dust particles in heating and cooling Earth's atmosphere on global and regional scales. https://photojournal.jpl.nasa.gov/catalog/PIA25145
