SCIAMACHY on ENVISAT has now successfully operated 4 years in space. The ambitious scientific objectives required an operations concept which fully exploits the instrument flexibility but keeps the operational effort to an acceptable minimum. The concept, which had been developed in phase C/D, proved its capabilities in-flight and ensures that SCIAMACHY generates a continuous stream of high-quality scientific measurement data.
In this presentation we give an overview of how the instrument is operated on a routine basis with particular emphasis on the needs of the user community. This includes viewing geometries, e.g. limb-nadir matching, spectrometer settings but also calibration & monitoring requirements. The current in-flight performance of the instrument on system-level is presented showing the excellent status with a few minor in-flight non-conformances being described. An outlook on what can be expected from an extended mission finishes the presentation.
