Statistical Modeling of Extremes in Data Assimilation and Filtering Approaches



STRASBOURG, 23-26 JUNE 2008

 

 

 

 

 

Summary of the meeting :

The scope of this inter-disciplinary meeting (statistics and geosciences) is to foster new research perspectives between atmospheric scientists and applied mathematicians around one important geophysical research topic: data assimilation of extreme events. Mathematically, the class of models used in data assimilation corresponds to a state-space formulation in which the state equation drives the dynamics of the system and the observational equation integrates measurements with the state variables. Our two-day lecture and two-day workshop aim at taking advantage of recent developments in the field of Extreme Value Theory within a state-space modeling and filtering framework.

 

Scientific Programme of the two-day lecture (23-24 June) :

We will have four invited speakers for these two days:

- Richard Davis (Columbia University) : Extreme Value Theory
- Olivier Cappé (ENST): Filtering Approaches
- Frédéric Chevallier (Laboratoire des Sciences du Climat et de l'Environnement ): Data Assimilation

Registration

·   There is no registration fee.

·   The participants (List ) are expected to have their expenses covered by their home institutions or from other sources. In case of extreme financial need, the participants are encouraged to contact guillou@math.u-strasbg.fr for an eventual financial support.

·   Please register via the registration form *** at your earliest convenience but before April 25, 2008.

Since only a limited number of places are available (30), the registrations will be attributed according to the principle: "first come, first accepted".

Practical Information:

·   Location:

The Institute is located on the campus  Esplanade (see the map below), which is near the city center . It is the number 36 on the map. The exact address is the following :

Institut de Recherche en Mathématique Avancée (IRMA)
7 rue René Descartes
67084 Strasbourg cedex
FRANCE

All the talks will be in the IRMA's conference room situated on the ground floor.

·   Lunches:

Tuesday and wednesday , sandwitches, cakes and drinks will be offered to all the registered participants, whereas a buffet (free) will be organized on Thursday.

·   Travel:

- From the station:

·   by foot, it takes about 30 minutes if you have a map;

·   by tram, in the train station you take tram A, direction Illkirch Lixenbuhl , to the station " Homme de Fer". Then you go out of the tram and take another one, Tram C, direction Esplanade, and you stop at " Universités ". After leaving the tram, undertake in the street Edmond Labbé. On the left, opposite the bar "Metro", the institute occupies a seven floor building whose entrance is situated at the opposite side.
