Abstract : The report presents results of transmission measurements in the visible and thermal infrared range along a slant path of 2.7 km length and 19 deg inclination. To infer correlating, all meteorological parameters, visibility, aerosol spectrum are measured at both ends of the path. For monitoring the aerosol distribution along the path serves a four-frequency lidar (ranging between 380 and 1060 nm). Transmissivity and extinction coefficient in VIS and IR are parameterized considering the following quantities: Clouds, mist, haze, aerosols, rate of rainfall, and snowfall. (Author)
