COVID-19 Earth Observation Dashboard Tutorial

The video tutorial explores how satellite data from NASA, ESA, and JAXA are used to observe the impacts of COVID-19 lockdowns on Earth. It covers economic indicators like import production and electric lights, environmental indicators such as air quality and greenhouse gases, and water quality changes in areas like the Adriatic Sea and Venice Lagoon. The tutorial demonstrates how these data are visualized and analyzed using the COVID-19 Earth observation dashboard.
