“…The pervasive presence of these emissions over the entire globe makes them excellent proxies for remote sensing of the nighttime ionosphere and thermosphere (Meier, 1991;Stephan et al, 2001;DeMajistre et al, 2005;Zhang YL et al, 2006;Dymond, 2009;Zhang YL and Paxton, 2019;Kil et al, 2020;Wang YG et al, 2022). In the past two decades, space-based observations of these two resonant lines, particularly the 135.6 nm emission, have been used as a primary means for global-scale monitoring of the nighttime ionosphere at midto-low latitudes (DeMajistre et al, 2004;Kil et al, 2004;Fu LP et al, 2015;Qin JQ et al, 2015;Qin JQ et al, 2016;Eastes et al, 2017;Kamalabadi et al, 2018;Wautelet et al, 2019;Wautelet et al, 2021). In the literature, extensive works have been dedicated to the development of numerical methods for the retrieval of ionospheric parameters from the absolute intensities of these airglow emissions (Meier, 1991;Dymond et al, 1997;Qin JQ et al, 2015).…”
