Paper Abstract

Atmospheric refractivity sounding is of great importance to the meteorological and military applications. An experiment was conducted for sounding the atmospheric refractivity on the top of the Wuling Mountain in August, 2005. Profiles of the atmospheric refractivity were obtained by both the mountain-based GPS and the tomographic method. Comparison shows that there is a bias of -3.83N and a standard deviation of 7.03N between the mountain-based GPS and the radiosonde. A bias less than 1% among different receivers proves that the receivers tested can meet the demand of the radio occultation technique. A very good consistence among the profiles by the mountain-based GPS, the tomographic method and the radiosonde suggests the effectiveness of both the mountain-based GPS and the tomographic method, indicating the great potential in the future meteorological application.
