6S v 1.1 is a basic RT code used for calculation of look-up tables in the MODIS atmospheric correction algorithm. It enables accurate simulations of satellite and plane observations, accounting for elevated targets, modeling of realistic molecular, aerosol, or mixed atmospheres, use of Lambertian and anisotropic ground surfaces, and calculation of gaseous absorption. The β-version of the vector 6S has been extensively validated since the time of its release in May 2005, two years later it was transformed into version 1.1. In addition to the code, we also provide a special 6S interface which can help an inexperienced user learn how to use the code and build necessary input files.
