An emerging new direction in remote sensing for Earth science: the technology of GPS occultations
In this paper, we discuss recent technology developments that improve science return in the lowest 5 km of the atmosphere, an interesting region that is difficult to sound at high vertical resolution with other techniques from space.

Comparison of GPS/SAC-C and MIPAS/ENVISAT temperature profiles and its implementation for EOS AURA-MLS observations
A new generation GPS flight receiver was launched on the Argentinian satellite SAC-C in 2001. It has demonstrated the potential applicability for the continuous monitoring of the earth's atmosphere with radio occultation technology, and providing high vertical resolution profiles of temperature and water vapour data complementary to other sounding techniques.

Quasi-biennial Oscillations (QBO) as seen in GPS/CHAMP Tropospheric and Ionospheric Data
A viewgraph presentation on Quasi-biennial Oscillations (QBO) from Global Positioning System/Challenging Mini-Satellite Payload (GPS/CHAMP) tropospheric and ionsopheric data is shown. The topics include: 1) A brief review of QBO; 2) Characteristics of small-scale oscillations in GPS/CHAMP 50-Hz raw measurements; 3) Variations of lower atmospheric variances; and 4) Variations of E-region variances.
