Terms of Reference and Objectives

Sub-commission 2.1 promotes scientific investigations of gravimetry and gravity networks by employing a three-step strategy. The first step is focused on gravity determination at some selected sites with absolute gravimeters (point scale). It provides the gravity community with means to assess the level of accuracy of steadily growing numbers of absolute gravimeters through organizing international inter-comparison campaigns of global and of regional scales. In the second step, the Sub-commission proceeds from the 0-D point-wise gravimetry to 1-D gravimetry: accurate and precise gravimetry/gradiometry around land/sea boarders where significant bias or errors are still observed. The Sub-commission promotes such research and development by stimulating airborne gravimetry and gradiometry. In the third step, it encourages and promotes special absolute/relative gravity campaigns, techniques and procedures for the adjustment of the results of gravity surveys on a regional scale (2-D). The Sub-commission will encourage regional meetings or workshops dedicated to specific problems, where appropriate.
