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.
