Understanding Water Storage Dynamics in Afghanistan: An Integrated Perspective

Water is a vital resource for livelihood and development, yet its availability is increasingly at risk due to climate change and anthropogenic activities. More than 80% of...

Calibration and Characterisation of GRACE-FO Magnetometers

Scientific satellites for measuring the Earth's magnetic field such as CHAMP (2000 to 2010) and Swarm (since 2013) contain a number of special instruments (scalar magnetometers,...

High-resolution groundwater storage changes from GRACE/GRACE-FO using assimilation models and hydrogeological observations

Using assimilation models and hydrogeological observations, a team from the Polish Geological Institute and the Space Research Center of the Polish Academy of Sciences has...

Ocean tide signals detected in GRACE and GRACE Follow-On distance measurements

In a recently published study, researchers from the Leibniz University Hannover introduce an innovative approach to reveal ocean tide model errors and unmodeled ocean tide...

Probing the atmosphere with GNSS radio occultations

The diverse sensor technology of the GRACE-FO satellites not only enables the measurement of the time-varying Earth's gravity field and the water mass shifts that cause it, but...

Observation of long-term changes in the East African Rift‘s hydrology with GRACE and GRACE-FO

For over 20 years, the GRACE and GRACE-FO satellite missions have observed changes in the water masses on the continents, the so-called terrestrial water storage (TWS). This data...

Evaluating long-term trends in terrestrial water storage from a joint analysis of 20 years of GRACE/ GRACE-FO data

The spatial resolution of the GRACE missions is limited, partly by the amount of sensor data required to process a global gravity field. Data over a period of 30 days is typically...

A new way to quantify groundwater decline from space

Terrestrial water storage changes (∆TWS) induce changes in Earth’s gravity field, measurable by the Gravity Recovery And Climate Experiment (GRACE) and its follow on mission...

Revolutionizing Earth Observation: The CARIOQA mission

The CARIOQA (Cold Atom Rubidium Interferometer in Orbit for Quantum Accelerometry) mission is an European Union funded project aimed to develop a new technology to be used in space...
