Pressure image assimilation for atmospheric motion estimation
The complexity of dynamical laws governing 3D atmospheric flows associated with incomplete and noisy observations makes the recovery of atmospheric dynamics from satellite images sequences very difficult. In this report, we face the challenging problem of estimating physical sound and timeconsistent horizontal motion fields at various atmospheric depths for a whole image sequence. Based on a ve...
متن کاملOptical-Flow for 3D Atmospheric Motion Estimation
In this paper, we address the problem of estimating three-dimensional motions of a stratified atmosphere from satellite image sequences. The complexity of three-dimensional atmospheric fluid flows associated to incomplete observation of atmospheric layers due to the sparsity of cloud systems makes very difficult the estimation of dense atmospheric motion field from satellite images sequences. T...
متن کاملExperiments with Atmospheric Motion Vectors at Ecmwf
Two new developments in extracting wind information by tracking of clouds or water vapour features are increasing the spatial coverage and providing quality estimates for individual observations. The transition from low density to high density wind observations of both GOES satellites led to first experiences with increased spatial coverage in NWP centres. The relative impact of low density and...
متن کاملMotion Estimation of 2d Atmospheric Layers with Variational Assimilation Techniques
In this paper, we aim at facing the problem of estimating time consistent mesoscale dynamics of atmospheric layers from satellite image sequences. Due to the sudden variations of the luminance function observed within clouds patterns and which are caused by the intrinsic sparse 3-dimensional nature of clouds, the estimation of accurate dense motion field is an intricate issue. Relying on a phys...
