Randolph H. Ware,Christian Rocken,Fredrick Solheim,M. Exner,William Schreiner,Richard A. Anthes,D. Feng,Benjamin M. Herman,Michael E. Gorbunov,Sergey Sokolovskiy,K. Hardy,Ying-Hwa Kuo,Xiaolei Zou,Kevin E. Trenberth,Thomas K. Meehan,W. Melbourne,Steven Businger +16 more
TL;DR: In this article, a low Earth-orbiting satellite using the radio occultation technique was used to obtain temperature soundings from a small research satellite, MicroLab 1, carried a laptop-sized radio receiver.

TL;DR: The Global Positioning System/Meteorology ( GPS/MET) Program was established in 1993 by the University Corporation for Atmospheric Research (UCAR) to demonstrate active limb sounding of the Earth's atmosphere using the radio occultation technique.
Journal ArticleDOI
The Promise of GPS in Atmospheric Monitoring
Steven Businger,Steven R. Chiswell,Michael Bevis,Jingping Duan,Richard A. Anthes,Christian Rocken,Randolph H. Ware,M. Exner,T. Vanhove,Fredrick Solheim +9 more
TL;DR: An overview of applications of the Global Positioning System (GPS) for active measurement of the Earth's atmosphere can be found in this paper, where GPS signals are delayed due to the presence of water vapor.
Journal ArticleDOI
A GPS/MET Sounding through an Intense Upper-Level Front.
Ying-Hwa Kuo,Xiaolei Zou,S. J. Chen,W. Huang,Y.-R. Guo,Richard A. Anthes,M. Exner,Douglas Hunt,Christian Rocken,Sergey Sokolovskiy +9 more
TL;DR: In this article, the GPS/MET sounding is compared with nearby radiosonde observations to assess its accuracy and ability to resolve a strong mesoscale feature, and the results showed that high-quality GPS/met radio occultation data can be obtained even when the occultation goes through a sharp temperature gradient associated with an upper-level front.

Atmospheric refractivity profiling apparatus and methods
TL;DR: In this paper, the authors described a system for characterizing atmospheric refractivity and its evolution in time and space utilizing passive radiation emission measurement devices. But the system can observe to any vector in the sky, giving directional as well as zenithal measurements of the refractivities profile, its spatial and temporal gradients, and the spatial and time trending of the profile and its gradients.
