Stakeholder consultation: Contribute to the Global Gravity-based Groundwater Product (G3P)

For the G3P project, the consortium aims at developing a product of groundwater storage variations with global coverage and monthly resolution from 2002 until present by a cross-cutting combination of GRACE and GRACE-FO satellite gravity data with water storage data that are based on the existing portfolio of the Copernicus services. 

Complete the survey

To ensure that this product will be of use to potential users, various stakeholders have been requested to participate in a user requirements survey. The consortium invites policy makers, commercial users, academic users, scientific and data organisations or any other interested individual to fill out this survey and thereby help to create the ideal global gravity-based groundwater product.

About G3P

Groundwater is one of the most important freshwater resources for mankind and for ecosystems. Due to its fundamental role in the Earth’s water and energy cycles, groundwater has been declared as an Essential Climate Variable (ECV) by GCOS, the Global Climate Observing System. 

The Copernicus Services, however, do not yet deliver data on this fundamental resource, nor is there any other data source worldwide that operationally provides information on changing groundwater resources in a consistent way, observation-based, and with global coverage. This gap will be closed by G3P, the Global Gravity-based Groundwater Product.
