■ World-class lightning observation network "JLDN"The lightning strike information obtained by "Pinpoint Thunderstorm" is acquired by JLDN (Japanese Lightning Detection Network).
JLDN is a national lightning observation network operated by Franklin Japan.
It is composed of 31 sensors from Hokkaido to Okinawa, and is an observation network that seamlessly covers the whole of Japan.
JLDNs lightning positioning accuracy has an average position error of 300 m or less, which is almost the same accuracy as the global large-scale lightning observation networks such as NALDN (North America) and EUCLID (Europe).■ How to use[Basic operation]Turn on the GPS function and start the app.
Information on lightning strikes within a radius of 50 km from your current location is displayed on the map.
