The SUMO is an aircraft build by the Geophysical Institute of the University of Bergen, Norway.
It uses industry standard sensors for temperature, air pressure, humidity and wind speed/direction as well as more specialized sensors as infrared/visible light radiation, particle concentration or ionizing radiation (full list). It has been successfully used in many measurement campaigns by various research institutions.
