Studies of Tides and Instrumental Performance of Three Gravimeters at Cueva de los Verdes(Lanzarote, Spain).

Abstract

Data from continuous observations with three Lacoste & Romberg gravity meters at station Cueva de los Verdes (Lanzarote, Canary Islands) are analysed. The tidal analysis shows, in general, a good agreement between the three meters. Correction frorn load and attraction effects permits to obtain better results when regional and local ocean models are considered, together with global ocean charts. The air pressure effect on two gravimeters exhibit important instrumental discrepancies.
