Look at all the Aerosols Pushed into the Atmosphere, from Fires, Volcanoes and Pollution. Even Sea Salt... / https://www.universetoday.com/?p=139836

Stand outside and take deep breath. Do you know what you’re breathing? For most people, the answer is simple – air. And air, which is essential to life as we know it, is composed of roughly twenty-percent oxygen gas (O²) and seventy-eight percent nitrogen gas (N²). However, within the remaining one-percent and change are several other trace gases, as well as few other ingredients that are not always healthy.

For instance, taking a deep breath outdoors, even on a clear day, will mean inhaling millions of liquid droplets and tiny solid particles. These latter bits of matter are what is known as aerosols, which refer to colloidal suspensions of particles in air or gas. These potentially harmful particles can be found anywhere on Earth and, as a recent NASA visualization shows, can appear in large concentrations in our atmosphere.

The visualization comes from the Goddard Earth Observing System Forward Processing (GEOS FP) model, which relies on observations from Earth-observing NASA satellites to tracks the presence of aerosols created by wildfires, volcanoes, storms and other phenomena. These satellites include the Terra, Aqua, Aura and Suomi National Polar-orbiting Partnership (Suomi NPP) satellites.
