Use of data of satellite system for gravity recovery and climate experiment (GRACE) for studying and assessment of hydrological-geohydrological characteristics of large river basins

Analysis is given of a relatively new method for studying the distribution and dynamics of land water resources, which is based on measuring the anomalies of Earth gravity field with the use of GRACE satellite system. The international satellite experiment on determining the gravity and climate changes has been carried out since 2002 with the aim of making high-frequency (within the frequency range of 10900?C36000 GHz) measurements of time variations in Earth??s gravity field. The measurement method and the procedure of data processing and evaluating the hydrological-geohydrological characteristics of large river basins and regions based on GRACE data.
