Tango mission NO2 End-to-end simulator

Tango consists of two CubeSat platforms, Tango-Carbon and Tango-Nitro, flying in formation.NO2, while not a greenhouse gas itself, can serve as a constraint on CO2 emissions, because both NO2 and CO2 are frequently co-emitted from similar combustion processes. Due to the low atmospheric background concentration of NO2 better detection of CO2 emission plumes is possible.Analysis of NO2 levels provides additional information about the magnitude of CO2 emissions.Detector requirements of the Nitro and Carbon instruments are analyzed using The Tango End-to-end simulator. It consists of a suite of modules that address all aspects of the mission data flow.In this contribution we will describe the NO2 branch of the simulator.
