Abstract
By using solar spectrum intensity measurements, the aerosol optical depth and the atmospheric turbidity coefficients of Bahrain's atmosphere, i.e. the Linke turbidity factorT and Ångström coefficientβ, have been calculated at discrete wavelengths from 350 to 800 nm. A linear regression model was fitted forT versusβ for such a humid climate and it was compared to models reported for desert (Dhahran, Saudi Arabia) and temperate (Avignon, France) climates. A relationship between the linear regression slope,b, and the function of concentration and size distribution of particles,α, over wide wavelength range was found.
