G11A:
Earth and Planetary Rotation: Improving Theories, Models, and Observations I Posters


Session ID#: 10692

Session Description:
Variations in the rotation, precession, and nutation of the Earth and other planets are caused by processes both external and internal to them. For the Earth, the increasing accuracy and temporal resolution of the observations provided by current and next generation measurement systems allow smaller amplitude and higher frequency signals to be observed, motivating improvements in both theories and models of Earth rotation variations. For the other planets, new missions to them will allow better understanding of their rotational variations. These improved theories, models, and observations allow greater understanding of the many processes that are causing the rotation, precession, and nutation of the Earth and other planets to change. This session will be a forum for discussing the improved theories, models, and observations of variations in Earth and planetary rotation.
