On 8 April 2015 at 14:09:36Z, the Lightning Imaging Sensor (LIS) on the TRMM satellite was powered off for the last time. The TRMM LIS mission has been recording both cloud-to-ground and intracloud lightning flashes from space since November 1997. However, preparations continue for the deployment of a second LIS instrument to the International Space Station in February 2016. LIS Level-2 lightning flash and background image datasets, as well as Level-3 climatologies, are available from GHRC.
