Section: Application Domains
The first and priority application domain is atmospheric chemistry, since this is the research topic of CEREA. We have at our disposal the 3D Eulerian chemistry transport model Polair3D and its adjoint, thus capable of data assimilation. Atmospheric data processing will aim at providing Polair3D with relevant input data.
A second application domain is oceanography. The objective is comparable: providing oceanic circulation models with relevant information, extracted from satellite images. This information is ingested within models using data assimilation techniques. The application domain is getting of crucial interest owing to the numerous satellite sensors providing relevant information on oceanographic modelling.
A third application domain is meteorology, in particular the forecast of extreme events. Problematics concern the identification and extraction, from satellite images, of precursors of extreme events, for further assimilation within conceptual meteorological models.
Finally, Clime carries out applied remote sensing approaches in close cooperation with environmental experts. These studies concern the potential use of satellite data for monitoring agriculture and natural risks: monitoring of land cover changes, assessment of hail damages, soil degradation (deforestation, desertification) and fire plumes. For these studies, an image model of the observed phenomenon is first established, then tracking and change detection techniques are applied in the state space of this model.
