Estimation of Extinction Coefficient of Solar Radiation under Cloudless Sky in the Atmosphere of Thailand
Abstract
This research objective is an estimation of the extinction coefficient of solar radiation in the atmosphere of Thailand. Solar radiation data from measurements and calculations using a theoretical model on cloudless days were used. The data was collected from four meteorological stations which located on Chiang Mai, Ubon Ratchathani, Bangkok, and Songkhla during 2013-2017. It was found that, the extinction coefficient of solar radiation was correlated in the mathematical model with the precipitable water vapor and visibility data. The correlation coefficient was 0.86. The extinction coefficients were calculated from the model are closed to those obtained from solar radiation data. The result indicating that both data are not significantly different at the confidence level 95%. The model was used to calculate the extinction coefficient of solar radiation from 85 meteorological stations throughout the country. The results showed that, the extinction coefficient of solar radiation were high at lower latitudes and also high in February to April.
