Using artificial intelligence methods to understand and forecast atmospheric quality parameters

摘要

Quality of life is strongly affected by the quality of the environment. Understanding and managing urban air quality is one of the main concerns of city authorities. For this purpose, it is important to extract knowledge and to be able to model the problem under investigation (air pollution), in order to be able to forecasts parameters of interest (pollutant concentrations). In this paper Artificial Neural Networks and Linear Regression models are used together with a set of mathematical tools that include Principal Component Analysis and Fast Fourier Transformations for the investigation and forecasting of hourly Benzene concentrations and highest daily eight hour mean of ozone concentrations for two locations in Athens, Greece. The methodology is evaluated for its forecasting ability. Results verify the suitability of the computational approach employed and the improvement of results in comparison to previous approaches.
