It is based on Environment Canada's weather stations in and around the Edmonton area (approximately a 60 km radius of Edmonton). The Doppler data is used to detect severe weather such as tornadoes. These echoes are called "ground clutter" and they occur when a portion of the radar beam comes into contact with tall buildings, trees or hills. Avalanche Canada. See active alerts in Canada. So with the clutter caused by ground objects filtered out, the PRECIP-ET product provides a cleaner image close to the radar. The data dates back to Jan 1, 2000. Weather maps provide past, current, and future radar and satellite images for local, Canadian and other North American cities. When the energy emitted by the radar antenna strikes particles of precipitation, such as drops of water, snowflakes, ice pellets, or hail, a portion of that energy is reflected back to the radar. Ice? The Halifax, Nova Scotia radar encompasses the following areas: The Graduated intensity scale to the right of the map shows the amount of precipitation that has been detected by the radar. During the cold season, a different relationship is used to relate the reflectivity to a snowfall rate (in cm/h - PRECIP-ET-Snow). Storms closest to a radar site reflect or absorb most of the available radar energy. The standard radar product Environment Canada now presents on its website is called a "PRECIP-ET" (PRECIPitation-ExTended) product (replacing the previous PRECIP product).
