(CNN) – Around you are tiny particles floating in the air known as aerosols. When you look out of the world and look at the whole world, these aerosols can paint a picture of what's going on in the Earth's atmosphere, from weather patterns to natural and man-made events.
Such a picture is possible See here in these composite images from NASA, depicting the world as it was on the 23rd of August. The pretty clouds of blue, purple and red are representations of the different types of aerosols in the atmosphere collected from NASA's satellite data and measurements on the ground.
According to the NASA description of the images, Blue Sea Salt is the Red is black carbon (as you would expect from a fire) and the purple is dust. If you look at the patterns of these three aerosols, you can spot some important weather and climate events: hurricanes, where the blues meet closely; strong winds and dust storms in the violet clouds; and red patches of carbon over forest fires.
"Some of the events that appear in the visualization caused quite serious problems on the ground," reads the NASA description.
"On August 23, Hawaiians plunged into torrential rains and. As the hurricane approached Lane, the two tropical cyclones threatened Soulik and whip Cimaron, South Korea, and Japan: the plume of smoke over Central Africa is a seasonal phenomenon, and especially the farmer's produce ignited numerous small fires to preserve arable and pasture land. which burned in Canada and the United States. "
To be clear, the colors are not really like those aerosols look like space – certainly dust is not purple, and even the worst wildfire would not look so wild from so far away , It's just the magic of science. Well, that and many algorithms, imaging, modeling, data collection and so on.
