Measuring temperatures is something we do every day. But how do you measure the temperature of the entire Earth? This video introduces you to the Sentinel-3 satellite, our “thermometer in space.” You’ll learn how it measures the Earth’s heat from 800 km above, and what we can learn from it. We’ll look at fascinating thermal images, like one from a heatwave in Egypt. You’ll see how cities, deserts, and forests have different temperatures. In the end, we’ll explain why these measurements are so important for understanding climate change and extreme weather events.
