We retrieve atmospheric water vapour and carbon monoxide abundances from nadir data acquired by the Planetary Fourier Spectrometer (PFS) on board of the Mars Express orbiter. The analyzed absorption bands are those centred on 3845 cm-1 (2.6 μm) and on 4235 cm-1 (2.36 μm), respectively. The geographical distribution of water vapour and carbon monoxide in the Martian atmosphere highlights longitudinal wave phenomena. These could be related to the existence of atmospheric planetary waves. The longitudinal trends show a sinusoidal behaviour of the gaseous concentration with wave numbers s = 1 for CO and s = 2 for H2O, prevalently. The comparison between these trends and vertical thermal profiles, measured by PFS, suggests a relation between the wave number and the vertical distribution of the examined gasses.
