Analysis of Short and Long Wave Radiation over Bengaluru

Abstract

The surface radiative energy remains the primary component of the energy balance of the earth atmosphere system and is a central determinant of the earth‟s climate. Energy is exchanged between the surface and the air radiatively at visible and infrared wavelengths through conduction, convection or latently. This energy at the surface of earth is important to many inter-related research disciplines such as atmospheric sciences, hydrology, agrometeorology   and climatology. The incoming short wave radiation is a primary source for photosynthetic activity and the hydrological cycle. The availability of surface radiation is also important for architects and solar engineers. It gives an accurate estimate of the available solar energy resource. Energy exchange between land and atmosphere are important in climatic processes. In this paper, the diurnal and seasonal dynamics and variations of surface radiation components are investigated. One year data is used to emphasize the separate contribution of each radiation balance component. The analysis shows important results such as
