In the project RIFUGIO we combine our so-called complete gravity field models (project In-
tErMod, first period of SPP 1257) with altimetric data for which a full error propagation is
implemented in the processing. Thus we derive estimates of the ocean’s mean dynamic topog-
raphy with a regular covariance matrix. The overall goal of this project is to integrate this
information into stationary ocean models and to assess the effects of this data combination on
improving ocean models. The study focuses on the North Atlantic Ocean bounded by the lati-
tudes 30◦ S and 80(66)◦ N.
