Every time I watch the weather forecast, Doppler radar is mentioned. The meteorologists at my local television station rely on it to warn viewers about floods, thunderstorms, and potential tornadoes. On stormy nights, the meteorologist will interrupt regular programming. He will always say that Dopp...
It is an on-board, long-range, 2.5D sensor that is robust to adverse conditions. These characteristics mean that, among the other benefits that it offers, radar is capable of detecting stable environmental features under variable weather and lighting, making it ideal for tasks like ego-motion ...

weather radar measurementsurban drainage modellingMOUSEradar data resolution:LAWRThe resolution of distributed rainfall input for drainage models is the topic of this paper. The study is based on data from high-resolution X-band weather radar used together with an urban drainage model of a medium-...
In principle, LiDAR is a much more accurate technology than radar. LiDAR can detect objects that are small and far away. It can also be used to map the terrain and detect objects in real-time. If you want to detect larger objects, especially moving ones, radar is a possible choice. For...
The prevalent long term weather conditions in a particular area. Climatic elements include precipitation, temperature, humidity, sunshine and wind velocity and phenomena such as fog, frost, and hail storms. Climate cannot be considered a satisfactory indicator of actual conditions since it is based up...
So why would we want to use radar imaging sensors in satellites, why not just stick with a conventional camera? Cameras are cheap, they see everything, and even the biggest camera in space is not 300 meters in diameter! Well, consider this: radar works in nearly all weather conditions, ...
Both types of models use a similar process; the difference is scale. Weather observations are made with weather stations, weather balloons, buoys, radar, weather satellites and more, and data is collected on precipitation and thunderstorms, wind speed and direction, air temperature and pressure, an...

“In this last case, it is called clear-air turbulence, and it can be difficult to avoid because it doesn’t show up on the weather radar in the flight deck.” “Clear air turbulence is air movement created by atmospheric pressure, jet streams, air around mountains, cold or warm weather...
