Abstract

Accurately quantifying global mass changes at the Earth's surface is essential for understanding climate system dynamics and their evolution. Satellite gravimetry, as realized with the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) missions, is the only currently operative remote sensing technique that can track large-scale mass variations, making it a unique monitoring opportunity for various geoscientific disciplines. To facilitate easy accessibility of GRACE and GRACE-FO (GRACE/-FO in the following) results (also beyond the geodetic community), the Helmholtz Centre for Geosciences (GFZ) developed the Gravity Information Service (GravIS) portal (https://gravis.gfz.de, last access: 21 January 2025). This work aims to introduce the user-friendly mass anomaly products provided at GravIS that are specifically processed for hydrology, glaciology, and oceanography applications. These mass change data, available in both a gridded representation and as time series for predefined regions, are routinely updated when new monthly GRACE/-FO gravity field models become available. The associated GravIS web portal visualizes and describes the products, demonstrating their usefulness for various studies and applications in the geosciences. Together with GFZ's complementary information portal https://www.globalwaterstorage.info/ (last access: 21 January 2025), GravIS supports widening the dissemination of knowledge about satellite gravimetry in science and society and highlights the significance and contributions of the GRACE/-FO missions for understanding changes in the climate system. The GravIS products, divided into several data sets corresponding to their specific application, are available at 10.5880/GFZ.GRAVIS_06_L2B (Dahle and Murböck, 2019), 10.5880/COST-G.GRAVIS_01_L2B (Dahle and Murböck, 2020), 10.5880/GFZ.GRAVIS_06_L3_ICE (Sasgen et al., 2019), 10.5880/COST-G.GRAVIS.5880/GFZ.GRAVIS_01_L3_ICE (Sasgen et al., 2020), 10.5880/GFZ.GRAVIS_06_L3_TWS (Boergens et al., 2019), 10.5880/COST-G.GRAVIS_01_L3_TWS (Boergens et al., 2020a), 10.5880/GFZ.GRAVIS_06_L3_OBP (Dobslaw et al., 2019), and 10.5880/COST-G.GRAVIS_01_L3_OBP (Dobslaw et al., 2020a).
