{{No footnotes, date=December 2008 6SV1 (Second Simulation of a Satellite Signal in the Solar Spectrum, Vector, version 1) is an advanced radiative transfer code designed to simulate the reflection of solar radiation by a coupled atmosphere-surface system for a wide range of atmospheric, spectral and geometrical conditions. It belongs to the group of procedures called Atmospheric correction for the process of removing the effects of the
