Research Abstract

Understanding of relative humidity(RH) dependence of optical properties of atmospheric aerosols is essential to estimate their effects on radiation balance in the Earth's atmosphere. In this work, we have developed a cavity ring-down spectrometer to measure RH dependence of aerosol extinction coefficients. By applying the instrument to observational and laboratory studies, it is found that the refractive index, chemical compositions, and mixing states of aerosols play important roles to determine the RH dependence of extinction coefficients.
