For the first time three different remote sensing instruments &ndash; a sub-millimeter radiometer, a differential optical absorption spectrometer in the UV-visible spectral range, and a lidar &ndash; were deployed aboard DLR's meteorological research aircraft Falcon&nbsp;20 to validate a large number of SCIAMACHY level 2 and off-line data products such as O<sub>3</sub>, NO<sub>2</sub>, N<sub>2</sub>O, BrO, OClO, H<sub>2</sub>O, aerosols, and clouds. Within two validation campaigns of the SCIA-VALUE mission (SCIAMACHY VALidation and Utilization Experiment) extended latitudinal cross-sections stretching from polar regions to the tropics as well as longitudinal cross sections at polar latitudes at about 70&deg; N and the equator were generated. This contribution gives an overview over the campaigns performed and reports on the observation strategy for achieving the validation goals. We also emphasize the synergetic use of the novel set of aircraft instrumentation and the usefulness of this innovative suite of remote sensing instruments for satellite validation.
