Researchers at the University of Ghent, in collaboration with the Royal Meteorological Institute (KMI), are testing a groundbreaking method to measure rainfall using signals between mobile phone masts. Current systems such as satellites, pluviometers, and radars all have limitations, especially in hilly terrain like Belgium’s Ardennes.
The new technique relies on detecting signal weakening between masts caused by heavy rain, with telecom companies already monitoring these connections in real time. This approach could prove especially valuable in regions with limited measurement infrastructure, such as Central Africa, where mobile networks are widespread.
Beyond improving rainfall mapping, the method could enhance early warnings for floods, landslides, and even differentiate between wet and dry snow, aiding road safety planning. Researchers believe combining this technology with existing systems could lead to more accurate weather predictions and disaster prevention.
