Ozone transmittance in a model atmosphere at Ikeja, Lagos state, Nigeria

Abstract

Variation of ozone transmittance with height in the atmosphere for radiation in the 9.6m absorption band was studied using Goody’s model atmosphere, with cubic spline interpolation technique to improve the quality of the curve. The data comprising of pressure and temperature at different altitudes (0-22 km) for the month of December 2006 for Ikeja in Lagos State of Nigeria was used for the computation. Computed result showed that ozone transmittance increased with height, except for the altitudes 4km, 6km< Z ≤8km and 10km < Z ≤18km due to absorption by O₃.
