Monitoring Atmospheric Pollution: The Role of Skier Marquis Satellite

The video discusses the impact of fossil fuels on global warming, focusing on nitrogen dioxide emissions from transportation, industry, and power plants. It highlights the role of ESA's Envy SAT and its instruments, particularly the Skier Marquis, in monitoring atmospheric gases. The video explains how data from these instruments is used to map NO2 emissions and analyze trends, revealing high pollution levels in specific regions. Despite uncertainties, the data aids in understanding climate change and may influence policy decisions.
