On August 23, 2018 the identification and distribution of aerosols in the Earth's atmosphere is shown in this dramatic, planet-wide 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 America and Africa. Sea salt aerosols are in blue, swirling above threatening typhoons near South Korea and Japan, and the hurricane looming near Hawaii. Dust shown in purple hues is blowing over African and Asian deserts. The location of cities and towns can be found from the concentrations of lights based on satellite image data of the Earth at night. via NASA https://ift.tt/2orIqHS
Keith's note: I am not even sure where to start. I knew Paul for 30 years. He was truly the "man in the moon". I am not sure that there was any one person left among us who had that Apollo-era sort of knowledge of the Moon - its geology, its resources, and its untapped potential. He was an unrelenting advocate for lunar exploration and he will be truly missed. This is a tremendous loss for space science.. Ad Astra Paul.
