On the Numerical Exploration of Zero-Dimensional Greenhouse Model using Newton-Raphson and Steepest Descent Methods

Abstract

Study has showed that Greenhouse gases are the main contribution to global warming. Climate modeling is one of method to explain the influence of those gasses to global warming. Many climate modeling have been proposed to analyze global warming process. Among them, Zero-Dimensional model as the simple model is able to generally describe the influence factors of the climate process. It is important to know the characteristic of each parameter by re-examining the current model. The model derived by Boeker-Van Grondelle offers simple description of global climate processes occurred. The model is system equations consists of two equations and variables. The systems are being studied by using two numerical methods, namely: Multiple-Equation Newton-Raphson and Steepest Descent Method. The accuracy of both methods was analyzed to obtain the best solution to the system equations. The proposed solution was verifying by the result that previously published. Index Terms-Climate modeling, numerical methods, Newton-Raphson and Steepest Descent.

Characteristics of solar energy radiation on typical summer and winter days in Kuwait

“…Known as a clean energy that has no direct release of emissions, solar energy is also seen as a good alternative energy to address problems related to the environment that result from the combustion of fossil fuels, such as the greenhouse gas problem [1,2]. Two of the most common solar energy conversion devices are the solar photovoltaic (PV) and solar thermal energy systems.…”
