Description:
The German geoscience satellite CHAMP (CHAllenging Minisatellite Payload) has collected the currently longest available time series of GPS radio occultation (RO) data comprising nearly eight years. Around 570,000 occultation measurements were performed between Feb. 2001 and Oct. 2008. This time series is continued by the U.S./German GRACE (Gravity Recovery And Climate Experiment) mission. To generate a homogeneous and high quality long-term set of GPS-RO data for climatological applications and trend analyses, a consistent reprocessing is needed. Major objectives of the GEOTECHNOLOGIEN research project ATMO-CHAMP/GRACE therefore are: a) improve ment of the scientific GPS RO processing software, b) consistent reprocessing of the CHAMP/GRACE GPS-RO long-term data set applying this improved software and c) the demonstration of climatological applications for the long-term data set. In this paper the status of the CHAMP/GRACE processing is overviewed and climatological applications regarding global temperature and tropopause trends and irregularities of the ionospheric E-region are demonstrated.
