Abstract
This study presents a two-angle forward scattering (TAFS) method that can be used to detect atmosphere visibility and distinguish different weather phenomena. The visibility measuring instrument has two receivers arranged at the forward scattering angles of 35° and 90°, and the atmosphere visibility is measured by the first receiver (35°). We use the ratio between the scattering phase functions and to judge the asymmetry parameter of atmospheric particles and to distinguish the weather phenomenon. Compared with multi-angle forward scattering (MAFS) that can distinguish fog, haze, and mist, TAFS can determine additional weather phenomena (i.e., normal weather and rain) and has fewer receivers. Thus, we improve the instrument design of this method whose visibility error is smaller than that of MAFS on rainy days.
