One example was respectively pickedfrom near infrared spectra and the spectra which near infrared blended with the visible region here.Those spectra were analyzed. In near infrared, the strong band luminescence of 02 atmosphericband (0,1) has been identified as a clear spectrum for the first time. Because 02 atmospheric band(0,1) was identified by all excellent meteor train spectra observed at the same night, 02 atmosphericband (0,1) is the main luminescence in near infrared of the early stage meteor train of Leonids.The photon emission rate of 02 atmospheric band (0,1) has been estimated at 6e+16 photons/m/son average of 4-9 seconds after the meteor appearance.
