Comparison of GPS radio occultation soundings with radiosondes
[1] The radio occultation (RO) sounding technique that uses signals transmitted by the Global Positioning System (GPS) has evolved as an important global observing technology. In this paper, we compare RO refractivity profiles from the CHAMP (CHAllenging Minisatellite Payload) satellite mission with those calculated from radiosonde soundings over five geographical areas, each of which uses a di...

متن کاملStatus of GPS radio occultation with CHAMP
The German geoscience satellite CHAMP (CHAllenging Minisatellite Payload, launched on July 15, 2000, Reigber et al., 2002) is in orbit now for more than 2 years. CHAMP's measurements are used to determine Earth's gravity and magnetic field and to derive precise information about vertical temperature, humidity and electron density distribution on a global scale using the innovative GPS radio occ...
متن کاملGPS radio occultation with CHAMP : Initial results
Fig. 1. The German CHAMP satellite (view from antivelocity direction with GPS occultation antennas) Abstract: The German CHAMP (Challenging Minisatellite Payload) satellite (launched on July 15, 2000) is a geoscience mission aiming for the determination of Earth’s gravity and magnetic field and for GPS-based atmospheric sounding. The atmospheric profiling experiment onboard CHAMP was started in...
متن کاملGPS radio occultation with GRACE : Atmospheric profiling utilizing the zero difference technique
Radio occultation events recorded on 28–29 July 2004 by the " BlackJack " GPS receiver aboard the GRACE-B satellite are analyzed. The high stability of the receiver clock allows for the implementation of a zero difference technique rendering clock calibrations with concurrent observations of a reference GPS satellite unnecessary. Thereby the usage of ionospheric correction procedures for the de...
