Dual polarization: a leading-edge technology
These state-of-the-art radars will have fully integrated dual-polarization technology, which will enable forecasters to better distinguish between rain, snow, hail, and freezing rain as well as better discern the size, shape, and variety of precipitation particles. This technology will also enable better identification and removal of non-meteorological targets such as birds, bugs, and debris from the data. As a result, they will issue more precise and timely weather watches and warnings for these significant weather events, giving Canadians more lead time to take appropriate actions to protect themselves, their family, and their property from the effects of severe weather.
Extended tornado-detection range
The new radars will also have an extended severe-weather detection range to cover more of Canada, increasing the Doppler range to 240 kilometres per radar from the current 120 kilometres. Doubling the Doppler range will give Canadians greater lead time to protect themselves and their families from tornadoes and other severe weather. Extending Doppler coverage of the weather-radar network will also allow for better overlap of neighbouring radars in case of an outage.
Better serving weather-sensitive industries
Economic sectors sensitive to weather events such as agriculture, natural resources, fisheries, construction, aviation, tourism, transportation, retail, and investors will benefit from higher data quality and consistency for severe-weather events as weather information is an important part of their strategic planning. For example, weather-radar imagery is used to help in safely routing planes around severe weather.
The improved weather-data quality will also allow for more effective use of the information in other areas, such as water management, as radar images are used to understand the effects of precipitation on drainage basins, in particular in support of flood forecasting by provinces.
