Vertical atmospheric profiling by drones during the WMO UAS-DC campaign 2024.

Meteorological observations were made at the Meteorological Research Institute, Tsukuba, Japan, as a part of the WMO UAS-DC campaign from 1 March to 30 April 2024. We conducted drone observations for atmospheric structure profiling (temperature, relative humidity, wind speed, and direction) up to 900 m above ground level using three types of drones (PF2, Build Flyer, and Mavic3). The meteorological sensors were installed on the arm and top of the drone's body.
