Book Description
Abstract: Separate energy budgets for the lower atmosphere (0-11 km) and upper atmosphere (> 11 km) are obtained in this report. The Schuster-Schwarzschild (S-S) integral equations of radiative transfer (Schuster 1905; Schwarzschild 1906, 1914) governing the radiation through atmosphere are solved to obtain the radiative fluxes that are required for the energy budget. The back radiation obtained from this analysis agrees with Intergovernmental Panel on Climate Change (IPCC, 2007) data. The standard temperature, pressure and density data required for the analysis is obtained from US Standard Atmosphere (1976). This analytical procedure uses the standard assumptions like one dimensionality, effective absorption coefficient (k) for a mixture of gases, constant flux directional parameter and quasi-static equilibrium. For the lower atmosphere, it has been assumed that all the clouds lie in the 0-11 km region. The ground level value of absorption coefficient group (kp), (kp)o is also obtained. 'p' is the partial pressure of the mixture of radiative gases.
