Superconducting gravimetry has been proven to be extremely helpful when seeking answers to open questions related to temporal gravity variations in a wide range of geophysical and geodynamic research. This is especially true if superconducting and absolute gravimetry is combined. Within the framework of GGP (Global Geodynamics Project) about twenty superconducting gravimeters with a comparable instrumental standard are in operation since 1997. Recent results of different research targets are discussed covering important questions like those for the inner structure of the earth, atmospheric and environmental effects, atmospheric loading, ocean models and earth rotation. Some of these problems are closely linked to each other, and a successful approach to the solution of a certain problem often implies addressing additional questions. This applies to both data processing and interpretation. Another key issue for obtaining highly reliable results is the accurate calibration and the stability of both the gravimeter and the air pressure sensor. Some questions regarding instrumentation and station noise are discussed.
