Since April 1992 the orbit of the European remote sensing satellite ERS-1 is adjusted to a 35 day repeat cycle. This implies an equatorial ground track spacing of some 80 km only providing a unique opportunity for an altimetric monitoring of the sea surface with a high spatial resolution. At the German ERS-1 processing center (D-PAF) ERS-1 orbits are computed by means of globally acquired laser tracking data. In addition, altimetry derived sea surface height models are generated on a systematic and regular basis. The European Space Agency, ESA, has set up a fast delivery distribution providing processed altimeter data three hours after observation. Now both has been combined in a new way to generate a new product: a 35 day mean view of the sea surface that can be generated with a delay of a few weeks only. The first products show a spatial resolution comparable to what could be achieved up to now only by the combination of missions with different orbit characteristics. The general data flow and the processing chain for this new product are introduced.
