The globalwaterstorage.info information portal is complementary to GravIS. While GravIS is mainly addressing scientists and students who do not necessarily have to be experts in geodesy but at least have a certain basic knowledge about GRACE/-FO or mass change processes, it does not intent to provide more general background information about the technology and applications of GRACE/-FO.

Globalwaterstorage.info provides easily accessible information on GRACE/-FO to the interested public, media representatives, and political decision-makers and highlights the significance and contributions of the GRACE/-FO missions for understanding changes in the climate system. Short blog contributions cover individual aspects of the missions in easy-to-understand language. The blog covers scientific insights obtained from the mission data as well as technological aspects of the missions. It also provides regular updates on new activities related to the realization of future satellite gravimetry missions. Future blog posts shall also focus on describing the relevance of GRACE/-FO satellite data for applications, addressing the following questions. Why is terrestrial water availability so important? Which regions of the world are particularly at risk of water loss? What developments need to be done in the future? Furthermore, the portal provides a collection of topical dossiers and fact sheets and hosts a media library collecting infographics, videos, and animations connected to GRACE/-FO.
