WebDuring the last decade ground- and space-based GPS (Global Positioning System) techniques for atmospheric sounding came up as a promising tool for global, permanent, weather-independent and calibration-free remote sensing of the Earth's atmosphere and ionosphere with high accuracy. WebThe GPS (Global Positioning System) radio occultation experiment onboard the German CHAMP (CHAllenging Minisatellite Payload) satellite was activated in February 2001. By the end of 2001 about 36,500 occultations were recorded. We review the occultation data processing at the GFZ and discuss selected first results.
