Abstract
As an extension of the Mie lidar technique to measure the extinction
coefficient of the surface particles, a horizontally pointing Mie lidar is
used for determining the optical properties of Asian dust, which is an
approach without knowing the actual lidar ratio. A long lasting dust event
is observed based on this approach in May 2014. The “no dust,” “pure
dust,” and “polluted dust” stage is observed during this event, and their
optical and hygroscopic properties are discussed. Some new optical and
hygroscopic features are observed, which benefit from the quantitative,
multi-wavelength, and continuous measurement of the extinction related
optical properties of dust particles.
