Key Points
- The Lightning Imaging Sensor (LIS) has been providing data from the
International Space Station (ISS) since March 2017.
- ISS LIS provides storm-scale resolution (4-km) and millisecond timing
of global lightning with spatially uniform detection efficiency
(~60%).
- The 3-year global lightning climatology is consistent with previous
studies (within 5-10%), while extending results to higher latitudes.
