DHI has developed a short range high intensity weather radar to detect the spatial variation of local rainfalls. This is useful for providing rainfall forecasts with a few hours' warning.

Typically, the size of a rain cell on the radar is set at 100 x 100 m, 250 x 250 m or 500 x 500 m - depending on the type of application. The radar provides a high-resolution image of the rainfall pattern, usually every 5 minutes or (optionally) once per minute.

The radar measurements may be presented as time series of rainfall for specific catchments or as graphical images of the full radar coverage. This information can be broadcast to the web in real-time. DHI’s weather radar can also be combined with its urban drainage models and thus provide an integral part of urban information and flood management systems.
