Research Areas

Over its 40-year history of development and operation, the space geodetic technique called very long baseline interferometry (VLBI) has provided an unprecedented record of the motions of the solid Earth.

Since launch in 2002, data from the Gravity Recovery and Climate Experiment (GRACE) have provided a synoptic view of mass change associated seismic cycle and other processes [Figure 1}.  As part of the GRACE and now the GRACE-FO science teams,  we have studied the long-wavelength gravity signal associated with varied earthquakes, including the great subduction zone earthquakes (e.g. Sumatra, 2004; Maule, Chile, 2010, and Tohuku, Japan, 2011), as well as strike-slip and normal faulting events that also produce discernible gravity changes (e.g. 2012 Indian Ocean earthquakes, Han et al., 2015).

Earth possesses a strong magnetic field that is originated from the Earth’s fluid outer core (the intrinsic field). This field accounts for more than 95% of the magnetic energy of the observed geomagnetic field at the Earth’s surface. Its temporal and spatial variations hold some of the key knowledge of Earth’s deep interior properties, of interactions and responses between the fluid core and the solid Earth, and of the Earth system evolution history.

For more than four decades, satellite laser ranging (SLR) measurements have been monitoring changes in Earth’s dynamic oblateness, C20, which is the largest component of Earth’s time-variable gravity field. The launch of GRACE in 2002, and subsequent launch of GRACE-FO in 2018, has revolutionized the ability to track mass fluxes at a spatial resolution of 300-500 km. Early in the mission, however, GRACE-derived estimates of C20 were deemed unreliable, as evidenced by a non-geophysical 161-day periodic signal and trend estimates that differed significantly from those determined with SLR. Throughout the mission, SLR-derived C20 estimates have been used to replace the values obtained with GRACE.
