Descripción del proyecto
Mirar al cielo para encontrar agua bajo tierra
Bajo la superficie de la Tierra hay agua: en las grietas y espacios del suelo, la arena y la roca. Aunque es crucial poder detectar las aguas subterráneas, todavía no existe ninguna fuente de datos en todo el mundo que proporcione información sobre la evolución de los recursos hídricos subterráneos de forma coherente, basada en la observación y con una cobertura global. Para colmar esta laguna, el proyecto financiado con fondos europeos G3P reunirá a la ciencia y a la industria de toda Europa para mostrar las variaciones del almacenamiento de aguas subterráneas utilizando los datos sobre gravedad de los satélites GRACE y GRACE-FO. GRACE fue una misión satelital que estuvo en marcha entre 2002 y 2017. GRACE-FO llegó en 2018 para dar continuidad al conjunto de datos de GRACE. Aunque el enfoque del proyecto no es nuevo, sí tiene un alcance global y se basa mayoritariamente en datos de observación por satélite en lugar de en datos simulados.
Objetivo
Groundwater is one of the most important freshwater resources for mankind and for ecosystems. Assessing groundwater resources and developing sustainable water management plans based on this resource is a major field of activity for science, water authorities and consultancies worldwide. 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.
The G3P consortium combines key expertise from science and industry across Europe that optimally allows to (1) capitalize from the unique capability of GRACE and GRACE-FO satellite gravimetry as the only remote sensing technology to monitor subsurface mass variations and thus groundwater storage change for large areas, (2) incorporate and advance a wealth of products on storage compartments of the water cycle that are part of the Copernicus portfolio, and (3) disseminate unprecedented information on changing groundwater storage to the global and European user communities, including a European use case as a demonstrator for industry potential in the water sector. In combination, the G3P development is a novel and cross-cutting extension of the Copernicus portfolio towards essential information on the changing state of water resources at European and global scales. G3P is timely given the recent launch of GRACE-FO that opens up the chance for gravity-based time series with sufficient length to monitor climate-induced and human-induced processes over more than 20 years, and to boost European space technology on board these satellites.
