NOMAD/TGO and PFS/MEx joint analysis for trace gases retrievals in the Martian atmosphere

Trace gases retrieval in the Martian atmosphere is one of the key goals of the NOMAD spectrometer suite onboard ESA’s Trace Gas Orbiter (ExoMars/TGO). Planned and executed joint observations of NOMAD’s IR high resolution channels and MEx/PFS spectrometer data will be analysed using both instruments in Nadir and Limb observational geometry. Synergies and complementarities between the two instruments will be exploited to increase accuracy and confidence on the retrievals of trace gases, such as water and carbon monoxide, and aerosols.
