summary:
The Earth Surface Mineral Dust Source Investigation (EMIT) is an Earth Ventures-Instrument (EVI-4) Mission that maps the surface mineralogy of arid dust source regions via imaging spectroscopy in the visible and short-wave infrared (VSWIR). Installed on the International Space Station (ISS), the EMIT instrument is a Dyson imaging spectrometer that uses contiguous spectroscopic measurements from 410 to 2450 nm to resolve absoprtion features of iron oxides, clays, sulfates, carbonates, and other dust-forming minerals. During its one-year mission, EMIT will observe the sunlit Earth's dust source regions that occur within +/-52\302\260 latitude and produce maps of the source regions that can be used to improve forecasts of the role of mineral dust in the radiative forcing (warming or cooling) of the atmosphere.\n\nThis file contains masks for L2A estimated clouds and cloud shadow masks and geolocation data. Geolocation data (latitude, longitude, height) and a lookup table to project the data are also included.
