提出了一种测量气溶胶单次散射波长532 nm的新方法。该方法采用光腔衰荡光谱（CRDS）测量气溶胶消光系数（B（ext））和积分球浊度计测定气溶胶散射系数（B（scat））。该方法的一个独特之处在于，消光和散射测量是在完全相同的样品体积上同时进行的。消光和散射通道的检测限（3s）分别为0.61 μ m（-1）和2.7 μ m（-1）。
A new method for the measurement of aerosol single scatter albedo (omega) at 532 nm was developed. The method employs cavity ring-down spectroscopy (CRDS) for measurement of aerosol extinction coefficient (b(ext)) and an integrating sphere nephelometer for determination of aerosol scattering coefficient (b(scat)). A unique feature of this method is that the extinction and scattering measurements are conducted simultaneously, on the exact same sample volume. Limits of detection (3s) for the extinction and scattering channel were 0.61 Mm(-1) and 2.7 Mm(-1) respectively.
