Postdoctoral position : Assimilation of mobile observations at city scale with application to pollution

Version imprimable de cet article

he postdoctoral position aims to optimally assimilate observations, especially from mobile sensors, at urban scale. The objective is to devise data assimilation methods that (1) can deal with mobile observations, (2) properly take into account the uncertainties in the numerical simulations, and (3) are efficient enough to be applied in near real-time.
The assimilation of mobile observations raises interesting issues related to the assimilation of tracks instead of point observations. Also, the positions of the sensors are uncertain along those tracks.
The uncertainty quantification in the simulations is another key issue, especially at urban scale where the city geometry has strong influence on the error correlations. The numerical models are computationally intensive so that the propagation of the uncertainties requires to design surrogate models, e.g., based on Gaussian process emulators.
