Analýza mesačných modelov gravitačného poľa Zeme z misie GRACE

Abstract

Utilization of monthly Earth gravity models provided by the US-German mission GRACE (Gravity Recovery and Climate Experiment), focusing in particular on studying the detailed structure and time variations of Earth gravity field. The mission results are expressed using Stokes parameters. The seasonal variation of the gravity field is based on transformation of the monthly gravity field models into geoid model and analysis in terms of time development. Visualization of gravity changes caused mainly by the global water cycle and landscape hydrology.
