Satellite altimetry has been widely used in measuring ocean topography from space.The conventional altimeter system is the nadir radar altimeter system which has the limitations of one-dimensional mea
Using continuous 1-Hz sampling time-series recorded by a SG(superconducting gravimeter) at Hsinchu station, Taiwan of China, we investigate the anomalous gravit
Plasma scale height is an important parameter of topside ionosphere and contains information about ionospheric physics and dynamic. We investigated the seasonal
In this paper, we first transferred the normal height of ASTER GDEM v2 to GPS ellipsoidal height based on the EGM96, and analyzed the precision of this digital elevation model in the northeastern marg
