Observing the hydrology of China from space - detection of anthropogenic changes in hydrology using spaceborne measurements

In this study we focus on the use of remotely sensed data, mainly data from the GRACE mission, for the detection of hydrological changes in China. More specifically, the Hai - Huai - Huang basins and the impoundment of the Three Gorges reservoir are studied. Due to noise and the required filtering of the monthly GRACE gravity field solutions...

A Sensitivity Study into Strapdown Airborne Gravimetry

Airborne gravimetry is an important tool for the geodesy and geophysics communities. Able to provide medium to high-resolution measurements over large areas, it is the link between the low-resolution satellite measurements and expensive terrestrial campaigns, especially in remote areas. To explore the potential of airborne gravimetry, the...

Data assimilation of GRACE terrestrial water storage data into a hydrological model using the Ensemble Kalman Smoother: A case study of the Rhine river basin

Terrestrial water storage (TWS) can be defined as the storage of water on and below the land surface, and includes snow, ice, surface water, soil moisture, and ground water. TWS is a key component of the terrestrial and global hydrological cycles, which have important control over the water, energy and biogeochemical fluxes, and plays a major...

ICESat full waveform signal analysis for the classification of land cover types over the cryosphere

The Earth needs attention. That is the bottom line of today’s discussion on the impact of humans on the environment and their contribution to global warming. With the rapid sea level rise and the melting ice caps, it is becoming increasingly important to understand these processes. Mass balance estimates of the cryosphere (e.g. Greenland and...
