| Abstract: | The distribution of GPS slant observations taken by continuously operating Yangtze River Delta GPS network this work is described . The distribution of the grid coverage of slant data at different temporal and spatial resolutions are given. From this,the feasibility of 3D water vapor tomography in a test region is discussed. At last, a set of additional instruments in GPS network scheme for water vapor tomography is researched by using simulation method with ECMWF data. It is concluded that the bad geographic distribution of GPS network in Yangtze River Delta causes difficulties in tomography, and the overall accuracy can be improved by adding some stations, especially in lower atmosphere. |
| Keywords: | GPS slant delay water vapor tomography temporal and spatial distribution network encryption |
