It is also clear now that lightning can even expand tens or even, on rare occasions, across hundreds of kilometers. Map: NASA, public domain.įor instance, areas such as Lake Maracaibo in Venezuela, which has the highest intensity of lightning strikes in the world, has been determined to average 389 strikes per day. Global map of lightning strikes between 1995 – 2020 created using data from Optical Transient Detector (OTD) on the commercial OrbView-1 satellite and the Lightning Image Sensor (LIS) on NASA’s TRMM satellite, and the LIS mounted on the International Space Station (ISS). Increased geographic coverage now also means we have a better understanding of the global pattern of lightning strikes. ![]() Scientists now can use the new data to better measure not only location but horizontal and vertical extent of lightning strikes, giving them far more information about the intensity of a given strike. The main advantage of the new system is it can capture lightning in more northern and southern hemispheres, expanding out from the middle latitudes that the previous LIS focused on. Since the first LIS, a new LIS system has been installed on the International Space Station (ISS). New Lightning Sensors on the International Space Station The earlier tools were good at detecting the location of lightning, but were limited where lightning could be monitored, focusing mostly in the middle latitudes. It was clear, already early on, that potentially some lightning was being missed, particularly those with low signal. That satellite and system were active between 1995-2005, with the data mostly showing where lightning strikes occurred. The earlier Optical Transient Detector (OTD) sensor was also mounted on the OrbView-1 satellite, with the data used to make in 2001 of lighting activity.
