| Outline of Final Research Achievements |
An atmospheric radar (wind profiling radar) can continuously observe the height profiles of wind velocities with high temporal resolution. It is widely used for meteorological research, operational forecasting, and so on. Scattering targets of the atmospheric radar in the clear air conditions are fluctuations of radio refractive index due to atmospheric turbulence. Although the relation between temperature and humidity fluctuations and radar echoes has been discussed from the simultaneous observation with the radiosondes and has been generally explained, the difference between them is due to the difference between the observation volumes of radar and radiosonde. In this study, we measured directly over the MU radar with a small unmanned aerial vehicle (UAV) equipped with a meteorological sensor and simultaneously observed the same region. Observation field campaigns called the Shigaraki UAV-Radar Experiment (ShUREX) were carried out in 2015 and 2016.
