NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) is a cutting-edge mission designed to enhance our understanding of the role mineral dust plays in Earth’s climate system. Using an advanced imaging spectrometer aboard the International Space Station (ISS), EMIT measures the composition of mineral dust across Earth’s arid regions, which are major sources of airborne dust. The data collected helps scientists assess how different minerals, such as quartz, calcite, and hematite, influence climate by absorbing or reflecting sunlight and by interacting with clouds and ecosystems. By improving climate models, EMIT contributes to better predictions of climate change impacts and supports efforts to mitigate its effects.
