Simulated studies of water vapour tomography

Abstract: The technical success and availability of numerical algorithms have promoted the implementation of tomography to atmospheric sciences. The principal specific character in initial constraints, data collection and assimilation methods, obtaining the final numerical results and interpretation of these makes the continuation of the success story for GPS-tomography very challenging. Numerical simulation is the most time- and money efficient way to study different processes connected with tropospheric water vapour tomography. This paper gives a short overview of some mathematical methods for detection, monitoring and modeling of tropospheric water vapour. The possible mathematical approach to constructing a virtual ground-based sensors (GPS-receivers) network for a real geographical location and discretisation of the troposphere, also some aspects of raw data filtering and analysis are described. The outcome of tomographical modeling of the troposphere might to be applied to improve the results of large scale numerical weather prediction models. The questions of voxel geometry and methods of data processing are expected to be key questions in constructing an effective GPS-receiver network for water vapour tomography
