On a new wavelength with weather data

Swedish Meteorological and Hydrological Institute (SMHI), Sweden

Case  | 

Challenge

Detailed rainfall patterns with high resolution are difficult to monitor with existing technologies (radar, satellite and gauges).

Solution

Ericsson and SMHI leveraged cellular network data to measure rainfall in real time, utilizing signal disturbances in microwave links. By applying an algorithm, these disturbances can be used to measure exactly how much rain has fallen between two points on a microwave network.

Impact

Ericsson Weather Data creates detailed and cost-efficient rainfall and flood predictions using the existing telecom infrastructure. Potential use cases include climate mitigation efforts, flood prevention in sewage and stormwater systems in cities, agriculture, transport solutions, tourism, insurance, weather agencies and water utilities.

On a new wavelength with weather data

Major flood events are happening with increasing frequency worldwide, making access to more precise weather information an absolute necessity. Today’s weather technologies simply do not provide the time and spatial accuracy that is needed, so innovators at Ericsson and the Swedish Meteorological and Hydrological Institute (SMHI) have been leveraging microwave data to solve the problem.

“This project is a school book example of how collaboration between different organizations and industries should work. There are a lot of applications for this solution: micro-insurance in developing countries, flood warnings, and the ability to predict malaria outbreaks.”

- Jonas Hansryd, Head of Microwave Research
