Implementation of Hyperion sensor routine in 6S radiative transfer code

The Second Simulation of a Satellite Signal in the Solar Spectrum Vector code (6SV) is one of the most widely used Radiation Transfer (RT) codes, but its employment in the hyperspectral image pre-processing chain has been limited. Since version 1.1 (released in May 2007) some gaps in respect of Modtran accuracy were bridged, by taking into account the effects of polarization, thus additional validation work is required. This paper presents an implementation of the Hyperion sensor support in the original code and some tests on the use of modified model for the atmospheric correction of Hyperion archive scenes. First results of direct transfer simulation and model inversion to retrieve soil reflectance values are discussed in comparison with those obtained by Modtran-based algorithms.
