At the end of 2015, our UAV research lab at the French Civil Aviation University took part to an atmospheric research project with Meteo-France (CNRS-GAME and ENM) teams at the Atmospheric Research Center of Lannemezan (in the south of France).
This project, named VOLTIGE, aimed at studying the formation of cloud and fog events, with simultaneous measurements through multi-UAV flights. One of the planes is measuring the turbulence near the ground, a second plane is flying above the cloud or the fog with a radiation sensor and the last one is making a vertical profile of temperature, pressure and humidity up to 1500 meters AGL.
All the planes were controlled by Paparazzi UAV Apogee boards, with on-board logging on SD cards and navigation patterns triggered by sensors readings.
The video of the flights is finally on-line.
