Kinematic GNSS profiles in central East Antarctica

Satellite techniques allow a nearly global coverage of elevation data, even in polar regions. However, in situ observations are crucial to validate these measurements. This dataset contains 20 elevation profiles, observed by kinematic GNSS in central East Antarctica. They have been measured during scientific traverses of the Russian Antarctic Expedition between the Antarctic research stations Vostok, Progress and Mirny, spanning distances between 80 and 2900km each. The given elevations have been corrected for the height offset of the antenna above the snow surface and are thus surface elevation profiles refering to the WGS84 ellipsoid. For consistency with the measurements of satellite altimetry, they have been converted to the mean tidal system. For each epoch, estimates for the standard deviation are given, which are in the order of magnitude of 2 to 5 cm. Crossover analysis shows that independent profiles of the same season differ by slightly more (4 to 9 cm) as a consequence of vehicle dynamics while driving.
