Three payloads were operated in the framework of German Validation Activities:
The LPMA/DOAS payload contains a DOAS instrument providing stratospheric profiles of O3, NO2, BrO, and OClO. The DOAS instrument is flown together with the Limb Profile Monitor of the Atmosphere (LPMA) operated by Laboratoire de Physique Moleulaire et Applications/CNRS (France). The LPMA is an FTIR instrument providing stratospheric profiles of CO, CH4, N2O, O3, NO2, H2O, and CO2. Additionally, the DOAS instrument was absolute radiometric calibrated before and after each flight to derive solar irradiance.
MIPAS-B is an advanced cryogenic limb emission FTIR spectrometer providing stratospheric profiles of O3, H2O, CH4, N2O, NO2, ClO, temperature, and pressure.
The TRIPLE payload comprises the following in-situ instruments: cryogenic whole air sampler, Lyman-alpha fluorescence hygrometer, and ClO/BrO resonance fluorescence sensor. In addition, a tunable diode laser absorption spectrometer (TDL) providing in-situ measurements of H2O and CH4 shall fly piggy-back on the TRIPLE gondola.
Bremen contributions were the radiometric calibration for the DOAS payload and the TDL for the TRIPLE gondola. The following Table gives an overview about the flight performed:
