IAG Symposium "Earth Rotation and Geodynamics" at IUGG General Assembly


Dear Colleagues,

We would like to draw your attention to the "Earth Rotation and
Geodynamics" G4 symposium at the IUGG General Assembly in Montreal (July
8-18, 2019). This symposium will discuss recent progress of the studies
of Earth rotation and geodynamics using geodetic techniques. Relevant
geophysical phenomena include those associated with changes in Earth's
shape, gravity field and rotation. These include the wide spectra of
observational / analytical / theoretical studies of Earth rotation and
orientation such as polar motion, Universal Time or length of day,
precession and nutation, critical parameters for transformation between
terrestrial and celestial reference frames at the mm level required by
GGOS. Measurements of Earth's static and time-varying gravity field from
space-based and ground-based sensors, including comparison of results to
models. We encourage researchers to contribute early results from the
GRACE Follow-on mission. In terms of solid Earth deformation, relevant
research includes those related to tidal processes (solid Earth and
ocean loading tides), Earth's free oscillations, crust and mantle
deformation due to tectonic motions and isostatic adjustment etc. as
well. Studies with traditional techniques and historical data are also
encouraged to be contributed.

Best regards,

Convener: Manabu Hashimoto (Japan)
Co-Conveners: Janusz Bogusz (Poland), Jianli Chen (USA),
Matt King (Australia)
