"Meteorological services and partner institutions in many countries are seeking to improve their system for collecting, processing and broadcasting weather-related information to increase the resilience of their communities."

In 2013, a public-private partnership between Direction Nationale de La Meteorolgie (NMS of Guinea, West Africa) and Earth Networks paved the way for the first-ever operation of a comprehensive technologically advanced early warning system for monitoring and alerting to severe weather in a Least Developed Country (LDC).

The goal of the project is to enable and strengthen the Guinea NMS organization's ability to actively monitor thunderstorms and precipitation and issue timely and relevant early warning of dangeorous weather conditions.


This Early Warning System (EWS), implemented in just weeks, is enabling real-time weather observations and forecasts, Dangerous Thunderstorm Alerts (DTA) and radar-like visibility to precipitation, which can then be used to assess the possibility of floods and drought.

The EWS is an integrated large-scale system providing real-time resolution and maximum reliability to help Guinea officials observe, inform and alert the public and other government agencies to impending weather:

Observe 

  • Twelve (12) lightning sensors and weather stations, connected via the internet, were installed on Cellcom Guinee mobile telecom towers
  • Report real-time quality controlled surface observations as well as dangerous cloud-to-ground (CG) and in-cloud (IC) lightning that remains in the sky above extreme conditions
  • Total lightning is detected by a compact sensor that records and transmits flash waveforms
  • Real-time data transmission
  • Existing infrastructure was maximized by installing sensors on mobile cell phone towers in partnership with Cellcom Guinee
  • Network design and installation was completed within a four-week period

Inform and Alert

  • Total lightning data is utilized to create PulseRad and Dangerous Thunderstorm Alerts
  • PulseRad, a proxy radar visualization tool, provides radar-like visibility to highlight areas threatened by heavy rain,high winds, flash floods (accumulated rainfalls), as well as continual drought and flood potential monitoring
  • Dangerous Thunderstorm Alerts provide early warnings of severe weather
  • ENcast ensemble forecasting tool utilizes current weather and lightning data to enhance localized hourly forecasts
Project Impact

"Within a few weeks, it has become possible to actively track thunderstorms, monitor precipitation and issue alerts to severe weather across the country by utilizing innovative technology and the country’s existing cell tower infrastructure. 

Deployment and initial maintenance of traditional radar in a country like Guinea would require upwards of 10 million U.S. dollars which makes the new technology from Earth Networks a viable and exciting alternative for developing countries.”
