Method for reporting on precipitation using telephone network microwave data, which are sensitive to raindrops.
Ericsson and the Swedish Meteorological and Hydrological Institute (SMHI) have developed a method for reporting on precipitation using telephone network microwave data. The “Ericsson Weather Data” initiative builds on the knowledge that microwaves are sensitive to raindrops, and offer higher temporal and spatial resolution compared to existing radar solutions. As rain falls across the telephone network, real-time rainfall maps can be made by analyzing microwave signal loss patterns. This solution may be of particular interest to countries that lack an extensive weather-monitoring network but do have a microwave-based telephone network. It has been tested in Sweden, Germany and Rwanda, and aims to provide a high degree of early warning system foresight without the need for weather stations. Recent research on such microwave backhaul technologies from communication networks has suggested great potential for precipitation and flood monitoring in urban areas.
