NASA use satellite maps to track pollution trends – Daily Mail



Using new, high-resolution global satellite maps of air quality indicators, Nasa scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe. One of the atmospheric gases the instrument detects is nitrogen dioxide, a yellow-brown gas that is a common emission from cars, power plants and industrial activity. The US, Europe and Japan have improved air quality thanks to emission control regulations, while China, India and the Middle East have seen more air pollution.
