Abstract

The study presents a comparison of three methods for retrieving [O(3P)] altitude profile from emissions of O2(b, v’ = 0 – 2 --> X, v”) bands in the near IR spectral range of 629 – 997 nm. Based on balance equations of the forward problems, we obtained analytical expressions linking [O(3P)] to the volume emission rate for the corresponding transition in the framework of the YM2011 model [1]. The uncertainties of the retrieved values of [O(3P)] were estimated by the Monte Carlo simulation taking into account the errors of all model parameters [2]. Based on these uncertainties, it is possible to draw conclusions about the ranges of application of the suggested methods. Our results show that the retrieval of [O(3P)] altitude profile by using the emissions from O2(b, v’ = 1) can be applied only above 110 km with the relative uncertainty of 17 – 20%. As for retrieval of [O(3P)] altitude profile by using the emissions from O2(b, v’ = 2) and O2(b, v’ = 0), these methods can be applied in a wide altitude range of 90 – 140 km and 95 – 140 km, respectively. The relative uncertainty of these methods amounts 15 – 20% and 20 – 25%, respectively. This study was supported by the Russian Fund for Basic Research (grant RFBR No.17-05-00532).
