Improving Numerical Dispersion Modelling in Built Environments with Data Assimilation Using the Iterative Ensemble Kalman Smoother

Autor: Bertrand Carissimo, Patrick Armand, Raphaël Bresson, Marc Bocquet, Cécile L. Defforge

Publikováno v: Boundary-Layer Meteorology. 179:209-240

Air-pollution modelling at the local scale requires accurate meteorological inputs such as from the velocity field. These meteorological fields are generally simulated with microscale models (here Code_Saturne), which are forced with boundary conditi

Journal of Aerosol Science, 2019, 137, pp.105433-. ⟨10.1016/j.jaerosci.2019.105433⟩

In order to estimate the atmospheric impact of the release of sodium oxide aerosols from an indoor sodium fire, two chemical models describing the evolution of sodium oxide aerosols have been implemented in the atmospheric version of the computationa

Data assimilation at local scale to improve CFD simulations of atmospheric dispersion: application to 1D shallow-water equations and method comparisons

Autor: Raphaël Bresson, Marc Bocquet, Cécile L. Defforge, Bertrand Carissimo, Patrick Armand

International Journal of Environment and Pollution, 2018, 64 (1/2/3), pp.90. ⟨10.1504/IJEP.2018.099151⟩

International audience; Atmospheric dispersion modelling requires meteorological inputs over local domains with possibly complex topographies. These local wind fields may be difficult to simulate with CFD models, in particular because of their sensit

Scale-decomposed atmospheric water budget over North America as simulated by the Canadian Regional Climate Model for current and future climates

Autor: Raphaël Bresson, René Laprise

Publikováno v: Climate Dynamics. 36:365-384

Through its various radiative effects and latent heat release, water plays a major role in the maintenance of climate. Therefore a better understanding of climate and climate changes requires a better understanding of the hydrological cycle. In this
