2020 April 18 Just Another Day on Aerosol Earth Model Visualization Credit: NASA Earth Observatory, GEOS FP, Joshua Stevens Explanation: It was just another day on aerosol Earth. For August 23, 2018, the identification and distribution of aerosols in the Earth’s atmosphere is shown in this dramatic, planet-wide digital visualization. Produced in real time, the Goddard Earth Observing System Forward Processing (GEOS FP) model relies on a combination of Earth-observing satellite and ground-based data to calculate the presence of types of aerosols, tiny solid particles and liquid droplets, as they circulate above the entire planet. This August 23rd model shows black carbon particles in red from combustion processes, like smoke from the fires in the United States and Canada, spreading across large stretches of North…
