NASA’s EMIT Mineral Dust Detector Starts Gathering Data

How EMIT measures mineral dust in the atmosphere.

Mineral dust blown into the air is an important part of the Earth's system. Wind blows dust into the atmosphere from desert regions around the world, and can carry dust across oceans. Dark minerals that absorb sunlight can warm the Earth, while light-colored minerals can cool the Earth. By accurately mapping the composition of areas that produce mineral dust, EMIT will advance our understanding of dust’s effects throughout the Earth system and to human populations now and in the future.
