  abstract = {{W}e acquired continuous series of microgravity measurements using several {S}cintrex {CG}-3{M} gravity meters for several weeks in 1997. {T}he meters with 1 micro{G}al resolution were installed side by side in a stable reference station at the {ORSTOM} research centre to perform identical data acquisition. {W}e present and compare the instrumental responses obtained for the various gravity meters (measurement series of gravity field, standard deviation, internal temperature, tilts) and analyse their correlation with simultaneous recordings of meteorological parameters. {T}he data have been processed in order to establish the mid- to long-term relative stability and the accuracy of the instruments, estimate the contribution of instrumental effects to gravity data measurements and quantify the amplitude of the time variations of the gravity field that might be detected with such instruments. {T}his study emphasizes the sensitivity of some instrumental responses of the {S}cintrex {CG}-3{M} gravity meters (such as internal temperature or tilt) to local atmospheric-pressure variations. {T}his sensitivity can lead to non-negligible perturbations of the gravity measurements through automatic corrections applied in real-time mode by the integrated software. {W}e show that most of these instrumental artefacts can be easily removed in data post-processing by using simultaneous atmospheric-pressure data. {A}fter removal of an accurate {E}arth tide model, the instrumental drift and the instrumental effects, the temporal series are compared by computing differential signals...
