Investigation of mass distribution (water, ice and solid earth) caused by climate change
NASA GRACE follow-on science team; Lunar crustal structure from high-res gravity, topography, and seismic data; Superconducting gravity, gradiometer for planetary dynamics
Investigation of mass distribution (water, ice, and solid Earth) caused by climate change and natural hazards by analysing spacecraft radar and laser ranging, accelerometer, and GNSS instruments. Development of the high-precision cryogenic gravimetric sensor. Detection of the Earth's gravity has implication to satellite trajectory, positioning, guidance and navigation.
Competitive advantage
By precisely tracking the spacecraft trajectory changes, the satellite system can measure:
- amount of terrestrial water
- ocean tides, currents, gyres, and tsunami waves
- solid Earth deformation like earthquake and land subsidence
- polar region ice melts
Successful applications of research
- Quantification of global and regional sea level rise
- Determination of polar region ice sheet and glacier melts
- Solid Earth deformation by earthquakes
- Measurement of water resource changes over large river basins
- Detection of significant density change of the lunar crust laterally and vertically
