Aerosol indicatrices scattering of coastal haze

The results of aerosol scattering indicatrices calculations performed according to MaexPro model of the marine and coastal atmosphere surface layer are presented. The variability of indicatrices, including the halo part, from the relative humidity, wind regime, fetch, altitude and meteorological visibility range is considered. A strong dependence of the indicatrix on acceleration and wind speed is shown. At low fetch, the indicatrixes have a relatively steeper appearance, characteristic of coastal aerosol. With increasing fetch, the type of indicatrix becomes characteristic of marine aerosol. The data obtained show a strong dependence of the indicatrix on height and relative humidity.
