The Global lightning and sprite measurements (GLIMS) mission aims to study the generation mechanism of lightning-associated transient luminous events (TLEs) and the relationship between lightning and TLEs. Four types of sensors attached to the International Space Station are used to observe a lightning and TLEs. All four types of sensors work synchronously. Two complementary–metal–oxide semiconductor cameras at two different wavelengths (lightning and sprite imager: LSI) are used to capture a position of optical emission from lightning and TLEs. Six photometers at six different wavelengths (PHs) record an optical emission intensity at high temporal resolution. Each photometer works to detect an altitude of optical mission through the use of the optical spectrum that are absorbed by atmospheric gases. A very low frequency (VLF) receiver is used for recording Whistler mode waves from lightning. Very high frequency interferometer (VITF) with two VHF sensors estimates the radiation source direction using phase interference technique. In JEM-GLIMS mission, it is notable that it is possible to conduct a simultaneous observation of optical and radio instruments. The mission has been conducted since November 2012. In this paper, we will show the findings of experimental work conducted during the past 3 years (2013-2015).
