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.

Acknowledgments
We thank the CHAMP, GRACE and TerraSAR-X teams for their great work to make the GPS RO data continuously available. Our project was supported by the German Ministry for Education and Research within the GEOTECHNOLOGIEN programme (Research project NRT-RO) and also by GFZ basic funding. This project is also significantly aided by ECMWF, Met Office, Météo-France and Japan Meteorological Agency. We are very grateful for this support.
