Instrumentation scientifique de l’ATR 42 de Safire

Scientific instrumentation on the ATR 42 belonging to Safire, the French facility for airborne research. At the top, a mast carries a dummy microphysics measurement instrument that has been designed to comply with certification restrictions when it is necessary to fly without the instrument. Lower down, there is an isokinetic sampler that collects external air to supply chemical measurement or aerosol characterisation instruments. The ATR 42 is a plane that has been specially modified for scientific use. It is perfect for taking measurements in the middle troposphere, including measurements relating to chemistry, remote sensing, microphysics and turbulence. Safire is a unit dedicated to climatic and environmental research, satellite validation and aeronautical development. It uses planes for the benefit of scientific research as part of experimental campaigns.
