Unofficial 6S for easy isofit integration and argument updates
This is an unofficial repository for the Second Simulation of a Satellite Signal in the Solar Spectrum vector (6S) code. Please see the official site for documentation, additional aerosol models, and the official code. The initial upload here used 6SV2.1 (2014), downloaded and included in 2025. Additional updates that may be implemented in this repository are not necessary sanctioned by the core development team. That rationalization for this asynchronous upload is to support additional capabilities (mainly inputs and outputs) from 6S that support additional sRTMnet emulator capabilities, which many ISOFIT workflows utilize.
The ISOFIT team expresses sincere gratitude towards the 6S team for all of their efforts.
