Because they influence air quality, human health, and climate. Because they are closer to Earth. Earth observation. Because they are hovering over the same spot on the equator. The process in which satellites emits its own signal to capture reflected measurements. The process in which satellites detects reflected light or radiation. It is observing and gathering data from afar. 1 Sentinel-3 2 Sentinel-5P 3 Sentinel-4 4 Sentinel-1 5 Sentinel-2 This satellite measures air quality and trace gases in real time on a regional scale. This satellite uses multiple sensors to measure sea surface topography, temperatures, and surface colours. This satellites measures air quality and trace gases on a global scale. This satellite uses radar imaging to monitor land subsidence, urban deformation, and forest changes. This satellite captures high resolution optical images of Earth's surface. 1 PROBA-V 2 Landsat 3 Biomass 4 Envisat A miniaturised satellite, equipped with a specialised vegetation instrument to provide global vegetation cover. Is the longest-running satellite program, used to provide data to help land managers and policy makers. When launched, this satellite will give provide detailed information on forest height and above-ground biomass. Is the biggest satellite ever flown, it monitored the Earth’s land, atmosphere, oceans and ice caps.
