View reflectivity and velocity images from NEXRAD doppler radars. These scans are interpreted by a computer and translated into an image.View cloud images as seen from space by geostationary satellites. Doppler Weather Radar ( TDWR ) are all programs of critical importance to us. A complete set of scans takes around 5 minutes to complete. See the latest Southeast Regional Doppler weather radar map including areas of rain, snow and ice on . A minimum of 360 additional specialists are required to bring. Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). See the latest Iowa Doppler radar weather map including areas of rain, snow and ice. This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. See the latest Illinois Doppler radar weather map including areas of rain, snow and ice. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. See the latest New York Doppler radar weather map including areas of rain, snow and ice. The radar instrument receives a signal from this reflected energy during its listening period. A small fraction of the scattered energy is directed back toward the radar. See the latest Wisconsin Doppler radar weather map including areas of rain, snow and ice. A weather radar can determine the precipitation type (rain, snow, hail. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The Weather Radar Map Live page shows areas where precipitation is currently expected. The radar emits a burst, or pulse, of energy. NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy.
