    • ...Early studies of the plasmaspheric contribution using comparison between GPS-observed TEC values and TEC values derived from radio signals transmitted by Navy Ionospheric Monitoring System (1100 km LEO orbit) spacecraft [Lunt et al., 1999a] as well as ray tracing of the GPS signals through the numerical model of the plasmasphere [Lunt et al., 1999b] Figure 4. Tomographic maps of the ionospheric TEC obtained during relatively quiet prestorm ...

    • ...There is some arbitrariness to this designation, but it does correspond approximately to the altitude of the Transit (or Navy Ionospheric Monitoring System (NIMS)) satellites, allowing operational measurements of the separate ionospheric contribution to TEC [Ciraolo and Spalla, 1997; Lunt et al., 1999c], with the plasmaspheric contribution being RADIO SCIENCE, VOL...
    • ... selecting an appropriate effective thickness for the combined ionosphere and plasmasphere, but the situation is further complicated by the separate variation of the plasmasphere in response to storms, with a considerable depletion of the plasmasphere directly following the storm and a gradual replenishment (with a timescale of about 10 days) until the occurrence of a subsequent storm (usually before achieving complete replenishment) [Lunt et ...
    • ...The comparable investigations by Lunt et al. [1999c] were accompanied by prior model validations [Lunt et al., 1999b] and equatorward latitudinal exclusions for the GPS TEC calibrations, to minimize the plasmasphere influence...

    • ...The plasmaspheric contribution is fairly uniform as a function of time of day, with typical values for the latitude range of interest on the order of 1-3 TECU [Lunt et al., 1999a, 1999b]...
