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.

Global Ionospheric TEC Variations During January 10, 1997 Storm
The ionospheric storm evolution process was monitored during the January 10, 1997 magnetic cloud event, through measurements of the inonospheric total electron content (TEC) from 150 GPS stations. The first significant response of the inonospheric TEC to the geomagnetic storm was at 0300 UT as an auroral/subauroral enhancement around the Alaskan evening sector.

Global Ionospheric TEC Perturbations Monitored by the GPS Global Network During Two Northern Hemisphere Winter Storms
The global evolution of two major ionospheric storms, occurring on November 4, 1993 and November 26, 1994, respectively, is studied using measurements of total electron content (TEC) obtained from a worldwide network of ground-based GPS receivers.
