3. What it is used for A weather satellite is a satellite that is used to gather information about the weather. They will show a view of weather patterns over a large area. This allows meteorologists to track weather pattern and make accurate predictions about the weather. They can also be used for thermal imaging, X-ray sensors, high-energy proton detectors, alpha detectors, and energetic particles.
4. How it works They carry things called radiometers, they will scan the Earth for images. They detect visible, infrared, or microwave radiation to monitor the weather on Earth. All the information is transmitted to receiving stations that are on the ground. It takes less then a minute for the information to be readable. They will usually operate for about 3 to 7 years.
5. Extra Information Weather satellites travel in geostationary or polar orbits. Geostationary orbits provide views of the earth’s surface all day. Polar orbits go across earth’s surface and provide a view of the entire planet over the course of 12 hours. NASA uses Geostationary Operational Environmental Satellite or GEOS. The satellite in the western hemisphere is 2240 miles above Earth.
