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 (1PN 2 , 762, 630, 557.7, 427.8 nm), the relative intensity of the OH (9,3), O1D, O1S, 1NN 2 + and O 2 Atmosphere band (0,0) emissions in elves will be discussed. |
