[Kristel Chanard]

Dear Colleagues,

The next General Assembly of the EUROPEAN
GEOSCIENCES UNION will be held in Vienna and online, on April, 23 - 28,
2023.

We would like to draw your attention to the session G.2.2
Terrestrial Reference Frame: data analysis, evaluation and applications
[1] and encourage you to join us and submit an abstract to the session
!

Note that the ABSTRACT SUBMISSION DEADLINE IS TUESDAY, 10 JANUARY
2023, 13:00 CET.

Best regards,
Kristel Chanard 
On behalf of the G.2.2
conveners, Claudio Abbondanza, Mathis Bloßfeld et Susanne
Glaser.

G.2.2 Terrestrial Reference Frame: data analysis,
evaluation and applications [2] 

The Terrestrial Reference Frame (TRF)
is critical for monitoring the Earth's rotation in space, as well as for
many geoscientific applications that need absolute positioning and exact
orbit determination of near-Earth artificial satellites. Its new
realization, the ITRF2020 has been released based on the combination of
DORIS, GNSS, SLR, and VLBI station coordinate time series provided by
the IAG/IERS Technique Services.
The objective of this session is to
bring together contributions from individual Technique Services, space
geodetic data analysts, ITRS combination centres and all ITRF users,
with a broad range of applications from geosciences to society, to
discuss the results and scientific applications of ITRF2020 and other
realizations. The assessment of observed non-linear, and particularly
periodic, station motions through space geodetic techniques by
comparison with physics-based deformation models is of particular
interest. Moreover, contributions to geocenter motion determination are
encouraged. Finally, contributions that focus on identifying and
mitigating technique-related systematic errors as well as different
combination strategies, e.g., space and tropospheric ties are encouraged
because they may potentially enhance future ITRF solutions.
