Journees 2017 - First Announcement


The Observatoire de Paris and the Universidad de Alicante are pleased to
announce that the "Journees des Systemes de Reference et de la Rotation
Terrestre" (*) will take place from 25 to 27 September 2017 at the
University of Alicante, Spain. The Journees are supported by the
International Astronomical Union (IAU) and the International Association
of Geodesy (IAG).

In the interest of enhancing the interactions between Astronomy and
Geodesy these Journees are devoted to the study of the space-time
celestial and terrestrial reference systems and their evolution with
time, with the emphasis on the rotation of the Earth. The scope of the
meeting will range from concepts and theoretical solutions to
observational techniques and data analysis. 

The sub-title of this meeting is "Furthering our knowledge of Earth
Rotation" and addresses the challenges brought by the accuracy
requirements of the Horizon 2020 project. Therefore, our discussions
will help to develop the tasks of the IAU/IAG Joint Working Group on
"Theory of Earth rotation and validation", among others.

The topics of interest include, but are not limited to:
1. Theory of Earth rotation variations: precession/nutation,
   polar motion, LOD/UT1
2. Observation methods of Earth rotation variations:
   Earth Orientation Parameters (EOP) determination
3. Celestial and terrestrial reference systems and frames: improvements
4. Modelling of Earth rotation variations: solar system dynamics and
   global geophysical fluid mass transports
5. Relativity and new concepts in Earth rotation theory

Scientific Organizing Committee:
Co-Chairs: 
   Jose M. Ferrandiz (Spain) and Christian Bizouard (France)
Members:
   Aleksander Brzezinski (Poland)
   Benjamin Chao (Taiwan)
   Alberto Escapa (Spain)
   Richard S. Gross (USA)
   Robert Heinkelmann (Germany)
   Catherine Hohenkerk (UK)
   Cheng-li Huang (China)
   Sergei Klioner (Germany)
   Sebastien Lambert (France)
   Zinovy Malkin (Russia)
   Cyril Ron (Czech Rep.)
   Yaroslav Yatskiv (Ukraine)

Local Organizing Committee:
Tomas Baenas, M. Carmen Martinez-Belda, Juan A. Martinez,
Juan F. Navarro, Isabel Vigo.

Registration, submission of abstracts, proceedings and practical
information:
The web page of the Journees 2017 will be available soon at
http://web.ua.es/journees2017/. It will provide additional information,
instructions for on-line registration and abstract submission and other
useful information. Proceedings will be published at least on-line.

Hope to see you in Alicante!
Best regards
Jose Ferrandiz and Christian Bizouard (on behalf of the SOC)

(*) This meeting intends to keep the format and cover similar topics as
the successful series of Journees "Systemes de Reference
spatio-temporels" headed by Nicole Capitaine, whose concluding edition
was held in 2014.
