%X GPS radio occultation is a new technique that explores the global atmosphere. Both the inversion methods of geometric optics and full spectrum inversion are described in details. The geometric optics method is a classic inversion method used before. The full spectrum inversion can deal with the multi-path propagation problem frequently occurred in the lower atmosphere for which the classic method usually becomes inefficient. A new inversion scheme which combines the geometric optics method and the full spectrum inversion method is proposed for atmospheric radio occultation inversion. It is applied to data processing with one GPS/MET radio occultation event data and one CHAMP event data, and successfully yielding atmospheric parameter profiles, which suggest the combined method is an efficient inversion scheme.
