Postdoctoral Researcher for project "Global Gravity-based Groundwater Product" (G3P)

Vous êtes ici

The Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences is the national research centre for Earth sciences in Germany. With approximately 1.280 employees (including visiting scientists), the GFZ is conducting interdisciplinary research on the "System Earth" and the influence of humans on the planet. As a member of the Helmholtz Association, it is part of Germany's largest science organization.

The GFZ coordinates the project G3P (Global Gravity-based Groundwater Product) that has been granted in response to the Earth Observation Call EO-4-2019 of the Horizon 2020 European Union Framework Programme for Research and Innovation. G3P is a collaborative effort between twelve European institutions. The key objectives of the G3P project are: 1) to process and make accessible the latest satellite gravity data as water storage products, in particular from the recently launched GRACE-FO mission, 2) to advance existing Copernicus service products on water storage variations, and 3) to set up a global product of groundwater storage variations as a new cross-cutting application of the existing product portfolio of three Copernicus core services.
