Public-Private Partnership with Direction Nationale de la
Meteorologique Pioneers Use of Weather Monitoring and Alerting
Technology in GuineaObservation: Twelve lightning sensors and weather stations,
interconnected via the Internet, report a wide range of weather
conditions, and provide information on total lightning discharges.
Sensors follow both lightning that strikes the ground
(cloud-to-ground) and, most importantly, the vast majority of
lightning that remains in the sky (in-cloud) and above extreme weather
conditions. To maximize existing infrastructure, these sensors have
been installed on mobile towers, in partnership with Cellcom.
Reliability is enhanced through the public-private partnership in
which Earth Networks supports the Direction Nationale de la
Meteorologique by managing the backend IT infrastructure.
Information: Total lightning data powers a proxy radar tool
a patented, algorithm-driven visualization tool that provides
radar-like visibility to highlight areas threatened by heavy rain,
high winds, flooding and other extreme conditions. Just 12 sensors
enabled proxy radar coverage for most of Guinea and hundreds of
kilometers beyond for inbound storm tracking. Additionally, real-time
lightning and surface weather data gathered from the sensors is used
a forecasting product that provides very detailed short- to long-term
high-quality weather forecasts.
Alerting: Direction Nationale de la Meteorologique can issue
Thunderstorm Alerts (DTAs), which are based on total lightning. In
the U.S., DTAs are issued automatically to millions of consumers,
organizations and government agencies, providing them with the fastest
warnings to oncoming severe weather. DTAs have been shown to alert 50%
faster than warnings based on other technology currently available,
providing 27 minutes, on average, of lead time.
GERMANTOWN, Md.--(BUSINESS WIRE)--
A public-private partnership with Guinea’s national meteorological
organization (Direction Nationale de la Meteorologique) and U.S.-based
Earth Networks is paving the way for the first-ever operation of a
comprehensive early warning system for monitoring and alerting to severe
weather within a least developed country (LDC).
With extreme weather increasingly taking a tragic and devastating toll
on lives and livelihoods in countries rich and poor, many countries like
Guinea in Africa are seeking ways to increase climate resilience.
Traditional monitoring and forecasting systems using radar come at high
cost, both to deploy and maintain, making them unsustainable choices for
developing countries. This demonstration project is bringing advanced
forecasting and severe weather warnings in Guinea into the 21st century
by offering radar-like visibility to precipitation, which can then be
used to assess the possibility of floods and drought. The technology
will also enable real-time, total lightning-based alerting to storms.
“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,” says Dr. Mamadou Lamine BAH,
Director DNM and President of Regional Association 1 (Africa) for the
World Meteorological Organization (WMO). “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
