      <gmd:abstract>
       <gco:CharacterString>The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy (IAG). IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.
 
      
 The gravimetric station Medicina/Italy operated by the Federal Agency for Cartography and Geodesy (BKG), Germany, and the Department of Physics and Astronomy (DIFA) at the University of Bologna, Italy, was established in 1996. Continuous temporal gravity and atmospheric pressure time series from the SG is made available to the IGETS data base hosted by ISDC (Information System and Data Center) at GFZ.
 
      
 The gravimetric station is located at the premises of the Medicina Radio Observatory (Northern Cross) of Istituto Nazionale di Astrofisica (INAF), 30 km south-east from Bologna in the southeastern Po Plain. The plain runs parallel to the Pede–Apenninic border and represents a sediment-filled foredeep, where a huge sedimentary deposition (more than 5000 m of thickness) occurred during the Plio-Pleistocene. The uppermost stratigraphic sequences in the Plain are made of alternating sands, silts and clays variably interbedded and normally consolidated.
 
      
 Since 1996, an almost uninterrupted time series of gravity and barometric pressure variations are acquired with SG C-023. In the same year a series of repeated absolute gravity measurements with different AGs started.
 
      
 Although the gravity building is not well thermally isolated, the air-conditioning system compensates main temperature variations, keeping the room temperature stable within a range of 5 K. The hut facilitates three pillars of concrete in one room, one used for the SG and two for absolute gravimeters. All pillars show a slight seasonal tilting due to soil consolidation. This effect is mostly compensated by tilt compensation system of the SG.
 
      
 Since June 1995 and November 2004, data from two ground water wells, one in a distance of 500 m, the other nearby, are recorded, supporting the monitoring of local water storage changes.
