Purpose of the flight and payload description

EdS (Effet de Serre) is the french term for greenhouse effect and is a multi-instrument experiment aimed to study the same scientific area. The instruments carried onboard the gondola were two laser diode spectrometers denominated PicoSDLA that measure gas concentrations (one CH4 and the other CO2) developed by the University of Reims; AIRCORE-Ufi the only not-French instrument, built by the University of Frankfurt in Germany aimed to measure greenhouse gases; a particle counter denominated LOAC developed by the Laboratory of Physics and Chemistry of the Environment and Space (LPC2E) in Orleans; and finally the quartet composed by AIRCORE-HR, that also measures greenhouse effect gases, B-bop that performs Ozone measurements, Sawfphy aimed to trace the water vapour concentration and Tsen to obtain pressure and temperature, all developed under the aegis of the Dynamic Meteorology Laboratory (LMD). All these instruments were mounted on a platform denominated CASOLBA (CAlibration de cellules SOLaires sur vol BAllon french for Balloon-Borne Solar Cell Calibration) which was developed in 1975 by CNES to transport a module containing solar cells to be calibrated to be used in different projects, which was reconverted to serve other tasks.
