The Superconducting Gravimeter (SG) C025 has been operating in Vienna since 1995 in order to study both tidal and non-tidal phenomena. Results from different analyses of the five years' SG record in Vienna are presented. E valuating gravity residuals in high temporal resolution offers the possibility to detect and to study interesting short-term atmospheric effects. Often they can be observed even if the air pressure varies only slightly. It is shown that such gravity signals are physically significant. Most probably they are caused by atmospheric processes connected with intensive vertical convection. The inherent residual offsets are of geophysical origin. This has to be considered when using automated procedures for the preprocessing of gravity data.
