NEXRAD Base Reflectivity

   Rain, snow, and hail can reflect considerable amounts of energy and thus are detectable by radar. Additionally, aerial biota such as insects, birds and bats, and particulates such as smoke, dust, and pollen also reflect radar signals. These reflected signals produce radar images.
