Being susceptible to the change of atmospheric conditions, the volume emission rate (VER) is very suitable to be used as a light source by passive remote sensing for measuring atmospheric wind and temperature. Thus, the VERs emitted from O-2(0-1) and O(S-1) of the nightglow at 80-120 km are studied in this paper. Based on the Naval Research Laboratory Mass Spectrometer Incoherent Scatter (NRLMSISE-00) model data and the ground-based airglow imaging interferometer (GBAII) instrument observation for a local time and place, simulated VER profiles represented by four layers are obtained for the nightglow of O-2(0-1) and O(S-1). The O-2(0-1) nightglow model peak values at 94 km on 6 December 2013 and 8 November 2011 are 8111 photons . cm (-3) . s (-1) and 8406 photons . cm (-3) . s (-1) , respectively; however, the O(S-1) VER peak at a higher altitude of about 96 km on 18 December 2011 is only 338 photons . cm (-3) . s (-1) . The upper atmospheric VER values have been derived to transfer into the ground-based detected column intensities by our GBAII prototype. The calculated column integrated emission rates (IERs) of O-2(0-1) for 0 degrees and 45 degrees zenith angles are 1.48 x 10(7) and 1.91 x 10(7) photons. cm (-2) . s (-1) , respectively; the calculated column IERs of O(S-1) are 5.53 x 10(5) and 7.03 x 10(5) photons. cm (-2) . s (-1) , respectively. Correspondingly, the detected column IERs obtained by GBAII are 2.43 x 10(7) for O-2(0-1) and 6.57 x 10(5) photons. cm (-2) . s (-1) for O(S-1). (C) 2019 Optical Society of America
