We present observed seasonal and interannual geocenter motion over 1993--1999 based on laser data on the LAGEOS-1, LAGEOS-2, and Topex/Poseidon (T/P) satellites as well as Doppler orbitography and radiopositioning integrated by satellite (DORIS) data from T/P. The amplitude and the phase of the space geodesy-derived seasonal cycles for each coordinate are further compared to the estimates based on surface mass redistribution on the Earth surface derived from various climatic data sources: surface pressure, soil moisture, snow depth, and ocean mass variations. Geodesy and climatic data present good agreement in terms of seasonal, still not for interannual, geocenter motion.
