What is the JLDN National Lightning Observation Network?

What is the JLDN National Lightning Observation Network?

We conduct accurate and reliable lightning observations in real-time, 24 hours a day.

JLDN (Japanese Lightning Detection Network) is a nationwide lightning observation network operated by Franklin Japan. It consists of 31 sensors from Hokkaido to Okinawa, creating an observation network that seamlessly covers all of Japan. The lightning location accuracy of JLDN is below an average positional error of 300 meters, achieving precision comparable to large-scale lightning observation networks such as NALDN (North America) and EUCLID (Europe). 【Examples of Data Utilization】 ■ Social Infrastructure ■ Life Protection ■ Industry ■ Accident Investigation ■ Research Institutions ■ Media *For more details, please refer to the PDF materials or feel free to contact us.

Information about JLDN

Information about JLDN

It enables extensive and high-precision observations and the provision of high-density observational data.

Franklin Japan observes lightning across the entire country of Japan through the world-class lightning observation network JLDN. It is possible to obtain stable and high-precision lightning data over a wide area. In Japan's land areas, the capture rate exceeds 90%, with an average location error of less than 300 meters. 【Features】 ■ A network of sensors installed at 31 locations nationwide ■ Utilizing accurate time information sent from GPS satellites to observe lightning strike location, time, current value, etc. ■ A high-density network with an average of 6 to 7 sensors participating for each lightning strike ■ Minimal decrease in lightning capture rate due to the failure of some sensors ■ Accurate and reliable observations available in real-time 24 hours a day *For more details, please refer to the PDF document or feel free to contact us.
