Energy exchange between land and atmosphere are important in climatic processes. In this paper, the seasonal dynamics
and diurnal variations of surface radiation components of agricultural crops are investigated. One year data are used to
emphasize the separate contribution of each radiation balance component. From the energy budget equation and FAO
empirical model, we compare the clear sky solar radiation and the incoming short wave radiation in order to highlight
aerosols and water vapor role in the studied area. The analysis show two important results: 1) The relevance of the short
wave radiation in the net radiation budget especially in the wet season and 2) The variations of the long wave radiation
were small. Analyses provide an understanding of net radiation seasonal variations in the northern part of Benin. |
