The special issue highlights the state of research efforts on the atmospheric electricity in Asia, particularly in Taiwan, China and Japan. In some ways, this can also be viewed as a commemorative issue for the ISUAL/FORMOSAT2 experiment, which officially ended its mission in July 2016. The first breakthrough on atmospheric electricity research in Taiwan was achieved through ground campaigns, including the investigations of transient luminous events (TLEs) near the vicinity of Taiwan [Su et al., 2002; Hsu et al., 2003] and gigantic jet [Su et al., 2003]. From 2004 to 2016, the satellite mission of ISUAL (Imager of Sprite/ Upper Atmospheric Lightning) onboard the FORMOSAT2 satellite was conducted, and a few important results are reported in [Hsu et al., 2017; this issue]. The ISUAL mission is a successful international cooperation between Taiwan, USA and Japan [Chern et al., 2003; Su et al., 2005; Chen et al., 2008]. The past and current TLE scientific missions include the Mediterranean Israeli Dust Experiment (MEIDEX) sprite campaign onboard the space shuttle Columbia in 2003 [Yair et al., 2003], a Japanese micro satellite SPRITE-SAT (2010-) [Takahashi et al., 2010], the Japan mission Global Lightning and Sprite Measurements on Japanese Experiment Module (JEM-GLIMS) on the International Space Station (ISS) from 2011 [Sato et al., 2015; Sato et al., 2017], NASA Crew Earth Observation program (2011-2012) [Jehl et al., 2013] and the Iriss mission by Denmark’s first astronaut, Andreas Mogensen (2015) on the ISS [Chanrion et al., 2017]. The upcoming orbit missions including ASIM (Atmosphere-Space Interaction Monitor) [Neubert, 2009] and TARANIS (Tool for the Analysis of RAdiations from lightNIngs and Sprites) [Farges et al., 2017]. The ISUAL mission besides being a pioneer atmospheric electricity program, also is a historic space platform dedicating to the study of TLEs in the middle atmosphere [Hsu et al., 2017; this issue].
