Abstract

Global and precise atmospheric satellite-based measurements with high temporal and spatial resolution are especially suited to characterize global change related atmospheric variations and to improve global numerical weather forecasts. Atmospheric research cannot be imagined without satellite measurements since the sixties, when the meteorological use of satellite data started. Especially data from passive multi-spectral radiometers contributed substantially to the understanding of global atmospheric processes. But these data from, e.g., MSU (Microwave Sounding Unit) and AMSU (Advanced Microwave Sounding Unit) are influenced by instrument and orbit changes, calibration problems, instrument drifts, and insufficient vertical resolution.
