AB: Imager of Sprites and Upper Atmospheric Lightning (ISUAL) is a scientific payload onboard the FORMOSAT-2 satellite. The ISUAL payload contains three sensor packages; an ICCD imager, a six-channel spectrophotometer, and a duel-band array photometer. As the FORMOSAT-2 motions from the southern to the northern night hemisphere, ISUAL looks across the track toward the local mid-night region to monitor the activity of transient luminous events (TLEs; sprites, elves, blue jets, gigantic jets, etc). In a given day, the field-of-view of ISUAL sweeps through most of the Earth's tropical and sub-tropical regions. With the long term and global observation data, ISUAL experiment strives to elucidate the characteristics, occurrence frequency, and global distribution of TLEs from space. After the first light on 1 July 2004, ISUAL has registered approximately two thousands TLE events as of the end of August 2005. In the talk, key results based on these data will be presented; including the major hot TLE zones, the spectroscopic characteristics of TLEs (sprites, elves, and jets), the electric characteristics of TLEs, the meteorological conditions for the occurrence of TLEs, etc.
