Scientific paper
The German CHAMP satellite was in orbit for ten years, two months, and four days providing us with unique nine years of continuous and globally distributed zonal wind measurements. During its life time CHAMP decayed from ~450 km to ~250 km altitude. The mission also coincided with the declining phase of solar cycle 23. Zonal wind readings are derived from the onboard triaxial accelerometer located at the satellite's center of gravity. The newly calibrated accelerometer data set is available from June 2001 - August 2010 and offers samples at 10 second steps which translates to wind readings every 76 km. The orbital precession of CHAMP covers all local times within 131 days if both the ascending and descending arcs are combined. In this paper we want to give an overview of the observed characteristics of the zonal wind making use of the complete CHAMP data set. From climatological studies we derive the local time/latitude distribution. A special feature is the fast zonal wind jet along the magnetic equator. Of particular interest are the wind pattern at high latitude and the longitudinal modulations of the zonal wind by nonmigrating tides.
