First Results from a Comparison of Ground-Based Ionospheric Measurements in the Southern Hemisphere and the USU Global Ionospheric Model

The F-layer parameters N_mF_2 and h_mF_2 have been derived from measurements made at two Antarctic stations for quiet days during the austral summer and winter of 1982. Siple (76°S, 84°W) and Halley (76°S, 27°W) are both sited near L≈4.2 and use essentially identical digital HF sounding radars. Even...
