It maps the mineral composition of the planet's surface by collecting data on spectra, or the various light wavelengths given off by various colors. Mahowald added that EMIT will "revolutionize what we can do." We can utilize that information to learn more about the effects of desert dust.ĮMIT was launched in July 2022 and is currently connected to the International Space Station (ISS). Scientists can determine how different minerals heat or cool the planet using the data in their climate models.Įvery kind of dust has a distinctive way of reflecting light for instance, white dust reflects heat from the sun, whereas "red and the black dust absorbs it," according to the author. What Is EMIT?ĮMIT (Earth Surface Mineral Dust Source Investigation) is the world's first space-borne image spectrometer is assisting in the mapping of dust hues. Currently, she is collaborating with NASA on a new device called EMIT. Mahowald is a professor of engineering at Cornell University in the US and has spent the past 20 years tracking dust around the world. Natalie Mahowald, a climate scientist, believes that by learning more about dust storms, we can make future plans. These tiny dust particles can be transported by winds thousands of kilometers away, endangering human health and way of life, CNN reported.Īccording to the UN, land degradation, drought, and climate change are to blame for a sharp rise in dust storms in recent years. Sand and dust storms can occur anywhere in the world. Scientists are mapping dust storms to better understand them because each type of dust has its own light-reflecting signature that can potentially help us prepare for our future.
