Aerosols are tiny solid or liquid particles in our atmosphere like dust, sulfates from pollution or volcanoes, wildfire smoke, and more. NASA’s GEOS model shows how these particles can affect the air we breathe—even from far away.

Tiny particles floating in our air. This visualization shows how tiny particles called aerosols move through Earth's atmosphere from August 1 to September 14, 2024, using NASA's Goddard Earth Observing System (GEOS) model. These particles, which include sea salt, dust, smoke, and sulfates, can travel thousands of miles and affect air quality and visibility far from their original sources. By tracking these movements, NASA helps communities prepare for changes in air quality and visibility while advancing our understanding of Earth's complex atmospheric system.

Has anyone noticed the millions of particles floating around? Here is what the sky looks like at up to x125 optical zoom. What are all those particles? Is it Spring in the air? Or pollution?

Smoke usually doesn't behave like a liquid, because its particles tend to rise, carried by convection currents. But there are conditions in which smoke can drip like water, especially when it can cool down and condense, becoming denser than air.

Intense heat from this large wildfire in Broward County, Florida is rising so rapidly that it’s cooling and condensing onto smoke particles, creating these towering pyrocumulus clouds. ☁️🔥Ash was even found on cars in Pembroke Pines. More than 11,000 acres burned so far. #FLwx

Microplastics have already been detected in the air and in the ocean. New research shows that plastic particles affect the distribution of water in clouds and the ocean’s heat conductivity. How could these findings help to adjust our climate models? Learn more via the link.

Respiratory viruses like COVID and the flu can be spread by coughing, sneezing, talking, singing or even just by breathing. When this happens, microscopic airborne particles called aerosols pass through the air. If you inhale an infectious particle, you could become unwell.

Tamil Nadu towns are dust bowls. Dust is the major contributor of air pollution in TN urban areas(60+%), our lungs are filled with dust particles. Bad road design, inept local bodies.etc make our cities unlivable. I hope new govt change it 📷-Udayarpalayam

This animation shows hourly measurements of Particulate Matter 10 micrometres or less in diameter (PM10) across the Po Valley from 1 January to 31 January 2024. The data was obtained from Copernicus ECMWF reanalysis modelled data. PM10 plays a pivotal role in the air quality dynamics of the Po Valley. Comprising various particles like dust, pollen and combustion byproducts, PM10 is inhalable and can impact respiratory health.

A rhinolith is a hardened mass or "stone" that forms in a parrot's nasal passage, causing breathing difficulties. It typically develops from a buildup of debris like dust, food particles, and dried mucus.

Every time we wash or wear synthetic clothes, we release tiny plastic particles—microplastics—into the air, water, and even our lungs. Microplastic exposure occurs mainly through ingestion and inhalation, especially in urban areas where fibers from synthetic clothing and degraded plastics enter the air. These particles don’t just pass through the body—they accumulate in organs like the lungs, brain, liver, and even the placenta, raising potential health concerns. Synthetic fabrics like polyester, nylon, and acrylic shed microfibers into water and air, exposing us through wear, laundry, and poorly vented dryers. There's more. Performance clothing labeled “waterproof,” “stain-resistant,” or “oil-repellent” often contains PFAS, known as “forever chemicals” because they persist in the body for years. PFAS have been linked to hormonal disruptions, immune dysfunction, and cancers, making it particularly important to limit exposure—especially in children. Opting for 100% natural fibers like cotton, wool, or hemp reduces microplastic exposure, while filters or laundry bags like Guppyfriend can trap fibers during washing. Gradual changes—like opting for natural fibers and using washing solutions that trap microfibers—can significantly reduce exposure without requiring a complete wardrobe overhaul.
