摘要: [1] We present a method for the retrieval of imaginary part refractive index desert dust aerosol at near UV wavelengths. The uses observations radiances 331 and 360 nm by Total Ozone Mapping Spectrometer, optical depth measurements Aerosol Robotic Network. derived values Saharan are significantly lower than previously reported values. average retrieved vary between 0.0054 0.0066 different geographical locations. results in this work good agreement with several recent investigations.
