WWLLN - World Wide Lightning Location Network


Program Description: The World Wide Lightning Location Network is operated by the University of Washington in Seattle with lightning location sensors at VLF (3-30 kHz). With a network of sferic sensors, regular maps of lightning activity over the entire Earth are produced. Research that can be done using this data include Lightening Climatology and Atmospheric Electricity Background.

Organization Description: Sensors are placed and operated by 50 different organizations around the globe. Data from the sensors is led by Prof Robert Holzworth of the University of Washington

Data Description: Each lightning stroke location requires the time of group arrival from a least 5 WWLLN sensors. These sensors may be several thousand km distant from the stroke. The geographical arrangement of the sensors is important: a lightning stroke which is enclosed by sensors is much more accurately located than one which is not so enclosed. Recent research indicates our detection efficiency for strokes about 30 kA is approximately 30% globally. Presently there are 50 WWLLN sensors, and they are in the process of expanding to 60 sensors within the next year or two.
