  abstract = {The quality of mean dynamic topography (MDT) models derived from an
	altimetric mean sea surface and a gravity field model mainly depends
	on the spatial resolution and accuracy of the particular gravity
	field model. We use an integrated approach which allows for estimating
	the MDT and its (inverse) covariance matrix on a predefined grid
	which is one of the requirements for ocean data assimilation. The
	quality and accuracy of the MDT directly reflects the quality and
	accuracy of the used gravity field model. For the first time, MDT
	estimates along with its full error covariance matrix based on GOCE
	data can be provided. We demonstrate the progress accomplished with
	GOCE processing and the valuable contribution of the GOCE gravity
	field models regarding the estimation of the MDT by showing results
	based on altimetric observations of Jason-1 and Envisat in combination
	with different GOCE gravity field models for the North Atlantic.},
