Subject: 'Descartes - Nutation': Call for participation
Dear Colleagues,
As you probably know, the European partners in the WG on 'Nonrigid Earth
nutation theory' have been awarded with the Descartes Prize. The total amount
of money that we have received is 300000 Euros. The European consortium has
decided to use the money for studies devoted to the understanding of the next
decimal of precession/nutation, from the theoretical point of view as well as
from the observational point of view.
To that aim, we have created the Project 'Descartes - Nutation' in which the
following activities shall be carried out:
1. Sponsoring one or two international conferences with particular emphasis on
precession/nutation. These meetings will be held in the frame of IAG/IAU
sponsored conferences or meetings such as the Journées Systèmes de
Références. The Descartes Prize money should cover some of the participants'
expenses, if necessary.
2. Support the exchange of PhD students or Post-docs (not older than 38
years), within the project in order to address questions and find solutions
in the frame of the subjects given at the end of this text.
3. A limited part of the available money could also be allocated for
exceptional travel grants for scientists of the WG.
This email is a Call for Participation.
The European consortium has decided to open this call to the international
community. We would like to get applications either from a host institution
willing to accept a visiting young scientist or from a candidate who wants
to go abroad. The ideas of the proposals should fit to the objectives of
the Project 'Descartes - Nutation' as stated above. The proposals should
describe the research in one or two pages and should be sent to me
electronically (v.dehant@oma.be).
Due to the limited amount of money available, the exchange of PhD students
or Post-docs should be limited to 6 months or for a very few of them to one
year.
If the application is from a host institution willing to accept a visiting
young scientist it should contain:
- the name of the supervisor who is responsible for the plan of research,
- the planned work of the team, and in particular of the new PhD student or
Post-doc,
- the objectives and the scope of research,
- the means and facilities offered by a host institution and the means needed
from the project,
- the scientist(s) needed, mentioning if the host prefers PhD or post-doc,
- optionally, the name(s) of the visitor. If the name is not given, the
selection can be done after acceptance of the project.
If the application is from a candidate who wants to go abroad it should
contain:
- the CV of the candidate, including list of the most important publications,
- the opinion from his research supervisor,
- the objectives and the scope of present and future research,
- the funding needed for going abroad,
- optionally, the invitation of the hosting institution. If not given, the
candidate can be put in a list for a further selection.
The deadline for submission is 10th of April, 2004.
The European consortium has settled a small sub-group (the so-called Advisory
Board) that will be in charge of reviewing the applications and make
proposals to the consortium. The decisions will be taken according to the
quality of the proposals and the available money, and will be shared with the
whole working group involved in the Descartes prize. We want the
administration to be totally transparent. If for any reason you need some
confidentiality, please mention it explicitly.
We also plan to organize a summer school as soon as possible for helping the
PhD and Post-doc students.
A kickoff meeting for our new project is foreseen at the next Journées
Systèmes de Référence in Paris, 20-23 September 2004.
If your name is not listed below and if you want to participate into the work
of the WG 'Descartes - Nutation', please do not hesitate to contact me. If
your name is listed but you don't want to participate any more in our
discussion, please mention it to me as well.
Please forward this information to any colleague or institution which might be
interested.
Hoping to receive news from you before April first 2004,
Veronique Dehant
Here are the areas where we have identified weaknesses and where proposals
should be established.
Level 1: transfer function for nutation:
1. Topographic coupling, electromagnetic and viscous coupling
2. Gravitational coupling involving lateral heterogeneities
3. Second order coupling
Level 2: luni-solar and planetary forcing
1. Coupling effects should be revisited (includes Earth rotation/nutation and
global Hamiltonian approach)
2. Global approach (transfer function and forcing, Hamiltonian approach)
3. Dynamical flattening
4. Parameters used in nutation expression
5. Relativistic corrections
Level 3: geophysical fluids
1. Diurnal ocean tides
2. Atmosphere at diurnal timescale
3. Ocean response to atmosphere, at diurnal timescale
4. Hydrosphere at diurnal timescale
5. Mass conservation problem
6. GGFC formatting problem
Level 4: Free modes
1. FCN
2. FICN
3. Other modes, such as inertial core modes
Level 5: Nutation observation
1. VLBI
2. GPS/Galileo
3. Combination
