Abstract. Satellite Laser Ranging (SLR) data have been analyzed by ourselves and other groups to provide ~imstes of the secular variations in the zonal harmonics of the geopotential field. While the SLR data available frum late-1992 onward me superior in satellite and temporal coverage (two station...
