PhD Position Mass Transport Modelling from GRACE/GRACE-FO Data

Published Deadline Location
15 Jul 5 Sep Delft

Job description

The continued observation of the temporal changes of the Earth's gravity field is essential for understanding mass transport, caused by processes in the oceans and atmosphere, by melting ice caps and glaciers, by large-scale ground water use, among others. Mass transport is an essential climate variable, and its monitoring is required for understanding climate change. It is also crucial for monitoring hydrological processes at global and regional scales, thereby providing information for water security relevant for agriculture and drink water supply of billions of people worldwide. Space-borne gravimetry, notably in the form of the Gravity Recovery And Climate Experiment (GRACE), GRACE Follow-On missions, has provided observations covering two decades, but their full information content remains underutilized. Without fully exploiting the spatial and temporal resolution of gravimetric data, the ability to separate the underlying geophysical processes is not possible, crippling our understanding of the effects of climate change. 

This research aims at providing novel mass transport products derived from space-borne gravimetric data coming from past, current, and future missions. This is achieved by innovative methodology, namely by uniquely constraining the data from these missions to geophysical models, thereby combining the strength of the underlying physical knowledge contained in such models and maximising the spatiotemporal resolution of the satellite on-orbit observations. Auxiliary information, such as precipitation records or altimetry data, will establish a suitable temporal evolution, and topography and surface properties will predict a realistic spatial mass distribution. 

The successful candidate will transform the application of gravimetric data in the various geophysical domains by providing mass change estimates with unprecedented spatiotemporal resolution at specific geographical locations and focusing on particular geophysical processes. 

The successful candidate will be responsible for pre-processing the GRACE data, building the mass transport models at selected geographical regions, and validating and improving their parameterisation.

The successful candidate will also be involved in education as MSc student co-supervisor and/or as project coach.
