Currently there is no reliable method for remote sensing of altitude profile of the [O(3P)] in the daytime mesosphere and lower thermosphere, but atomic oxygen is a key component in the mechanism of the atmosphere cooling by quenching of vibrationally excited CO2 molecules and also one of basic quencher of electronically excited components in MLT region. On the other hand, airglow emission in 1.27 µm IR Atm(0 - 0) band from O2(a1∆g, v = 0) has been used as a proxy for [O3] in MLT for over a decade. However, this method is not suitable for detecting of relatively rapid [O3] variations which occur due to the variability of the solar spectrum in the UV range (120 - 320 nm) and other space factors. The reason of above mentioned is the large value of photochemical lifetime of the O2(a1∆g, v = 0) molecule which is within τ O2(a) =3.102- 1.103s in the mesosphere and reaches 3.103s in the lower thermosphere.The aim of this study is revealing of proxies for retrievals of [O(3P)] and [O3].
