Session on Earth Rotation at AGU 2023


As part of the 2023 Fall Meeting of the AGU that will be held in San
Francisco, 11-15 December 2023, we would like to draw your attention to
the session:

G004: Climate and geophysical fluid signals in Earth rotation parameters
- variability and prediction

We encourage you to submit abstracts to this session. The deadline to
submit abstracts is Wednesday, 2 August 2023 23:59 EDT/03:59 +1 GMT. The
description of the session is given below.

G004 - Climate and geophysical fluid signals in Earth rotation
parameters - variability and prediction

This session is dedicated to contributions on accurate modelling and
prediction of Earth rotation with special focus on geophysical and
climate signals in Earth Orientation Parameters (EOP). We invite
contributions that explore links between Earth's rotation and other
quantities like geophysical fluids, climate signals, gravity field, and
others. We also welcome works that exploit different types of data to
explain the excitation of the Earth's rotation. We are also interested
in studies on the relationship between EOP variability and variability
in geophysical fluids due to climate variation or global climate change
signals on time-scales from days to centuries. Finally, given the
importance of EOP predictions to the operational determination of the
Earth's orientation, we welcome the results of EOP prediction using
modern techniques combined with high-accuracy observational data and
models. We also encourage contributions on predicting other geodetic
quantities like effective angular momenta or climate indices.
