Statistical modeling of extremes in data assimilation and filtering approaches

IRMA, 23-26 juin 2008

The meeting "Statistical modeling of extremes in data assimilation and filtering approaches" will be held in IRMA from June 23 to June 26, 2008.

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.

Organizing committee (ANR AssimilEx) :

- Armelle Guillou (IRMA) et Anne-laure Fougères (MODAL’X)
- Frédéric Chevallier et Philippe naveau (LSCE)
