How Invisible Aerosols Connect in Earth's Atmosphere

NASA’s Goddard Earth Observing System shows that we’re basically all living in one big Lava lamp. It uses data from one million weather observations every hour—satellite information, computer models, and ground measurements—to animate how tiny particles in the air swirl across the globe. The swirls? These are aerosols, tiny solid or liquid particles suspended in the air. Here NASA sorts these into four categories: black carbon (aka wildfire smoke), dust, sea salt, and sulfates (aka volcanic ash and pollution). These particles can travel thousands of miles, shaping weather and air quality far from their source. A hurricane in the Atlantic pulled in dust from Africa—plus plenty of sea salt. And smoke from wildfires in Canada drifted over to Europe. This animation uses six weeks of weather data from August and September 2024 to reveal how wildfires, hurricanes, sandstorms, and volcanic eruptions stirred global air currents. This map makes it clear that Earth’s atmosphere is one huge web of invisible connections. Turns out, the grooviest Lava lamp owes some of its glow to hurricanes, volcanoes, and wildfires.
