The list of things that these satellites can do and read, is quite long, the primary use is looking at cloud patters that help determine the weather in certain areas. Satellites are equipped with what are called radiometers. They measure electromagnetic energy that the Earth and the atmosphere reflect, scatter, transmit, and emit. The two types of radiometers measure visible light from the sun and radiation emitted from the earth’s surface or its clouds. When the visible light radiometers produce images, they represent sunlight reflected off of objects on the Earth, which could be clouds, water, vegetation or something else. The radiometers measure radiation wavelengths between 10 and 12 microns. When these radiometers produce images, it is representative of heat rather than light, cold is white and hot is black. These are beneficial because it gives information day and night, unlike visual imagery. The IR satellite images are used to tell if clouds are height or low based on temperature, cold means high clouds while warm means low. Knowing cloud heights and temperatures help determine where weather will be coming from, or what will be forming in the future. Visible images help determine cloud types based on their visibility. The visibility is based on the number of water drops in it to reflect light. Knowing cloud types helps determine where rain or storms are happening, where is starts or and where it will end. Less commonly used is water vapor imagery. It can be used in some situations when areas cant be seen visibly or are being covered by clouds hiding the temp
