Paper Abstract

Spatial remote sensing atmospheric correction algorithms validation remains a challenge particulary over land and coastal environment. To assess this type of algorithm in the case of MERIS scheme, we propose a methodology based on the use of in-situ extinction and sky measurements from the world-wide Sun radiometer network AERONET. The spectral dependency in the blue and red derived from the extinction measurements is used to parameterize an aerosol model defined by the Jung power law size distribution in a first step and a chemical composition represented by a refractive index. This model is used to compute the phase function, a main input to a radiative transfer code (successive order of diffusion based) that allows to simulate the atmospheric parameters (radiances, transmittances). A comparison between the diffuse transmittance from sky measurements and that simulated allow to check the validity of the proposed method. The context of the study is calibration and validation in remote sensing using only the radiative properties of the atmosphere. A sensitivity study of the method to various parameters and an error budget will be reported.
