High-resolution precipitation radar data for research project ISRV

2 June 2022

Intelligent flood risk warning based on radar data and measurement data from rain sensors

After providing the real-time data flow of our X-band radar in Aachen, the ISRV project (Intelligent Heavy Rainfall-Related Flood Risk Warning in the Transport Sector) now has access to high-resolution and timely data regarding precipitation fields and intensities over Aachen and the surrounding area.

This allows us to document rainfall events of interest to optimize the AI-based flooding models of the Institute of Hydraulic Engineering and Water Resources Management (IWW) at RWTH Aachen University (

At the same time, KISTERS delivered the first TB7 low-budget rain sensors to our partner 4traffic. These will be placed in the city area to measure the actual precipitation on Aachen’s roads by means of the 4traffic detector boxes ( to improve radar data. We are looking forward to the first results this summer!
