In-orbit imaging and radiometric performance prediction for flight model Geostationary Ocean Color Imager

Geostationary Image Simulation on Coastal Waters Using Hydrodynamic Biogeochemical and Sedimentary Coupled Models

“…This ratio depends on the amplitude of the signal and can also vary with the wavelength. The total noise can be considered as a white Gaussian noise with a standard deviation σb (13).…”

“…This approach cannot lead to the simulation of a geosynchronous image because the spatial coverage would be too low and the viewing and solar angles are not representative of the geosynchronous configuration. A second approach is the forward model, which consists of modeling the surface reflectance and the radiance at the top of the atmosphere, as a function of ground biophysical and geometrical parameters [13]- [15]. The first advantage of this approach is that the models take into account the viewing and solar angles, which are important for non-Lambertian surface like the ocean.…”
