In this paper we present the results of volume emission rate profiles of 5577A˚ and 8446A˚ dayglow emission at midlatitudes. A model is developed by taking into account the variation in solar EUV flux as a function of solar activity and uses recent cross section data. The thermospheric peak emission rate ratio V(5577)/V(8446) is studied as a function of local time at midlatitudes. This ratio is found maximum at local noon time. The ratio is comparetively larger in the afternoon sector than the forenoon sector. In addition, the sensitivity of emission rate (for both emission) to atomic oxygen composition is studied by varying the density of atomic oxygen in the model. At local noon time, when the atomic oxygen density is reduced to half in the model, the ratio V(5577)/V(8446) is about 6.0 and this ratio approaches to about 2.0 if the atomic oxygen density is made double. The photoelectron flux is found more sensitive to atomic oxygen density.
