The atmosphere in human living areas (0 to several hundred meters) is in the very low layer of the troposphere and is called the surface atmosphere or the atmospheric boundary layer. Traditionally, information about this surface atmosphere has been collected using ground-based instruments such as thermometers and hygrometers, but atmospheric behavior depends on altitude; the lower the altitude, the smaller the spatiotemporal scale, resulting in steeper and finer movements. Additionally, it is influenced by the surface conditions of land and sea, structures, and meteorological conditions such as temperature, humidity, and wind. There is a challenge in that conventional ground-based instruments cannot keep up with these small-scale spatiotemporal behaviors. In this study, we are developing an LED mini-lidar specialized for measuring the surface atmosphere and are advancing the visualization and analysis of surface atmospheric behavior.
