Earth Surface Mineral Dust Source Investigation
A NASA Earth Venture Instrument headed for the International Space StationVisit Mission Website
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. The maps of the source regions will be used to improve forecasts of the role of mineral dust in the radiative forcing (warming or cooling) of the atmosphere.
EMIT is being developed at NASA’s Jet Propulsion Laboratory and is scheduled to launch in 2022. The instrument will observe Earth from outside the International Space Station. Once it begins operation, EMIT data will be delivered to the NASA Land Processes Distributed Active Archive Center (DAAC) for use by other researchers and the public.
