Space Flight Center Scientific Visualization Studio Caption for Items 3-5: Atlanta in the Heat



Urban areas with high concentrations of buildings, roads and other artificial surfaces retain heat, creating urban heat islands. Satellite data reveal that urban heat islands increase surface temperatures compared to rural surroundings. This animation of Atlanta shows how cities retain heat from day to night. Credit: NASA/
