| Abstract: | Volume emission rate profiles of O(1 S) dayglow emission measured near equatorial latitudes on 30 Oct. 1992 and 20 Jan. 1993 by Wind Imaging Interferometer on the Upper Atmosphere Research Satellite (UARS) are analyzed. These are the first results of volume emission rates between 90 and 300 km near equatorial latitudes. The observed emission rates are compared with the theoretical model developed for measurement conditions. It is found that the modelled and the measured profiles show discrepancy near mesospheric peak at latitudes close to the equator. This discrepancy supports the idea of tidal effects on O(1 S) emission near equator. In addition, the effects of solar zenith angle (SZA) on volume emission rate profiles are also studied. It is found that the modelled and the measured profiles show discrepancy near mesospheric peak at latitude close to the equator. This discrepancy support the idea of tidal effects of O(1 S) emission near equator. In addition, the effects of solar zenith angle (SZA) on volume emission rate profiles are also studied. It is found that the thermospheric peak disappears when the SZA is greater than 80°. |
