Abstract :
The Imager of Sprites and Upper Atmospheric Lightning (ISUAL) experiment on the FORMOSAT-2 satellite inferred the global occurrence rates of sprites, halos and elves to be ~1, ~1 and 35 events/min, respectively [1, 2]. Hence, elve is the most abundant type of transient luminous events (TLEs). From analyzing brightness observed by ISUAL Imager through different filters (1PN2, 762, 630, 557.7, 427.8 nm), the relative intensity of the OH (9,3), O1D, O1S, 1NN2+ and O2 Atmosphere band (0,0) emissions in elves will be discussed.
