Project description:The project deals with a proposal, analysis, implementation and application of efficient numerical methods and parallel computing in geodesy. Numerical methods like the boundary element method, finite element method and finite volume method will be applied for the Earth's gravity field modeling as well as for the satellite data filtration using numerical solutions of partial differential equations on closed surfaces that approximate the Earth's surface. A parallelization of algorithms using MPI and large-scale parallel computations on clusters with distributed memory allows to reach a high level of the discretization and to achieve more precise numerical results. The obtained quasigeoid models will be used to estimate shifts and tilts of local vertical datums and to propose a realization of the world height system. The filtration of satellite geopotential models from the satellite missions GRACE, or GOCE, and filtration of altimetric data will aim to model variations of the gravity field and mean sea surface.
