Relier Pairs Test your satellite knowledge!Version en ligne Different satellites have different jobs and monitor different parts of the Earth, match the answers to the questions par Kirsty Shakespeare 1 Why are geostationary satellites better at monitoring a specific region? 2 Why do polar orbiting satellites take clearer images? 3 What does the acronym EO stand for? 4 What is active remote sensing? 5 Why is it important to to track trace gases? 6 What is passive remote sensing? 7 What is 'remote sensing'? The process in which satellites detects reflected light or radiation. The process in which satellites emits its own signal to capture reflected measurements. It is observing and gathering data from afar. Because they are hovering over the same spot on the equator. Earth observation. Because they influence air quality, human health, and climate. Because they are closer to Earth. 1 Sentinel-3 2 Sentinel-4 3 Sentinel-2 4 Sentinel-5P 5 Sentinel-1 This satellite captures high resolution optical images of Earth's surface. This satellite uses radar imaging to monitor land subsidence, urban deformation, and forest changes. This satellites measures air quality and trace gases on a global scale. This satellite uses multiple sensors to measure sea surface topography, temperatures, and surface colours. This satellite measures air quality and trace gases in real time on a regional scale. 1 Envisat 2 Landsat 3 Biomass 4 PROBA-V A miniaturised satellite, equipped with a specialised vegetation instrument to provide global vegetation cover. Is the biggest satellite ever flown, it monitored the Earth’s land, atmosphere, oceans and ice caps. When launched, this satellite will give provide detailed information on forest height and above-ground biomass. Is the longest-running satellite program, used to provide data to help land managers and policy makers.
