Least square prediction applied to gravimetric tides in Europe

Abstract

The observation of gravimetric tides, which started in a systematic way from the sixties decade onwards, has come presently to cover a great part of the world surface, mainly due to the efforts of the group of Prof. Melchior (Melchior, 1982) and the realization of transcontinental profiles. The density of information existing in Europe and collected in the data bank of the International Center of Earth Tides in Brussels allows to make prediction tests on the main tides harmonics. A first work in this direction has been made for the Iberian Peninsula (Vieira, Camacho, 1988). In this communication there is an extension of such work given to a considerable part of the european continent through the application of the least square prediction method for the obtention of a model of gravimetric tides for Europe; likewise there is an study made on the security and reliability of the model functioning in the area, data density and quality of those data.
