The Earth Surface Mineral Dust Source Investigation (EMIT) is an Earth Ventures-Instrument (EVI-4) Mission to map the mineral composition of arid dust source regions via imaging spectroscopy in the visible and short-wave infrared range. The maps of the source regions will be used to model the role of mineral dust in the radiative forcing (warming or cooling) of the atmosphere.
EMIT was developed at NASA’s Jet Propulsion Laboratory and launched on July 14, 2022. The instrument observes Earth from outside the International Space Station. EMIT data will be delivered to the NASA Land Processes Distributed Active Archive Center (DAAC) for use by other researchers and the public.
