Abstract
ICGEM is one of the five services coordinated by the International Gravity Field Service (IGFS) of the International Association of Geodesy (IAG) and has been serving to the community for almost two decades.The service provides the scientific community with an archive of static, temporal, and topographic global gravity field models of the Earth in a standardized format with the possibility to assign DOIs. Furthermore, ICGEM provides interactive calculation and visualisation services of gravity field functionals. Maintenance of such a service and development of new “demand-based” tools are of utmost importance to provide state-of-the-art products. In 2016, the ICGEM portal has been renewed to guarantee a smooth transition to future needs. The last remaining component of the previous ICGEM portal, the G3 Browser, has now been upgraded and integrated into the present ICGEM portal. The G3 Browser aims to compute time series of equivalent water height interactively and gives users the opportunity to compare different gravity model time series as well as impacts of corrections (e.g., GIA, C20) or filters. The G3 Browser is complementary to existing services such as GFZ’s GravIS portal which provides ready-to-use products based on GFZ and COST-G solutions with already applied corrections and filters. On the other hand, the ICGEM G3 Browser includes time series from further processing centres and institutions and different filtering options. This presentation includes the recent progress and how ICGEM and its components contribute to the gravity field related research and educational purposes in universities at graduate and undergraduate level.
