Evaluación de factores de turbidez atmosférica a partir de medidas de radiación solar global en el sector Centro-Oriente de Bogotá

Abstract

The sky is not totally clean, however, when the concentration of particles is greater than normal, it can attenuate solar radiation more intensely. So, the amount of solar radiation that reaches the earth’s surface depends largely on atmospheric turbidity. In this sense, solar radiation is attenuated through the atmosphere due to the presence of gas molecules, water vapor, clouds and aerosols; In a cloud-free atmosphere, solar radiation is attenuated by two main mechanisms, the absorption and scattering of incoming radiation by molecules and particles suspended in the air known as aerosols. The resulting reduction in transparency is known as atmospheric turbidity, this expresses the presence of aerosols in the atmosphere and is considered a parameter of the utmost importance for evaluating air quality in local areas. The main objective of this work is to evaluate the factors that cause atmospheric turbidity in the center-east of Bogotá, this is done by studying the data provided on particulate matter and global solar radiation obtained by the present stations of the RMCAB and the IDEAM in the localities of Bogota.
