This research aims to validate SAMSAT CubeSat with cheaper infrastructure alternative using up-to-date software and hardware. The study will be limited to processing raw image dataset from spectroscopic instrumentation which in effect will be used to validate the capabilities of nanosatellites. The research will specifically commit to globally map CO2, water vapor H2O, methane CH4, Oxygen, Ozone and hydroxyl radicals and then do a validation with GOES. The relevance of this research is to understand the impact of greenhouse gases on our environment.
