Global structure and composition of the martian atmosphere with SPICAM on Mars express

Bertaux, Jean-Loup; Dimarellis, E.; Forget, F. +26 more

SPectroscopy for the Investigation of the Characteristics of the Atmosphere of Mars (SPICAM) Light, a light-weight (4.7 kg) UV-IR instrument to be flown on Mars Express orbiter, is dedicated to the study of the atmosphere and ionosphere of Mars. A UV spectrometer (118-320 nm, resolution 0.8 nm) is dedicated to nadir viewing, limb viewing and verti…

First observations of the planetary Fourier spectrometer at Mars

Piccioni, G.; Grassi, D.; Khatuntsev, I. +8 more

The first results of the Planetary Fourier Spectrometer (PFS) orbiting the planet Mars are reviewed and discussed here, with reference to a set of studies being published elsewhere. An average global spectrum ranging from 200 to 8200 cm ^-1 is discussed by comparing it to the ISO SWS Martian spectrum and to the global synthetic spectrum …

Thermal structure of the Martian atmosphere retrieved from the IR spectrometry in the 15 µm CO₂ band: input to MIRA

Grassi, D.; Zasova, L. V.; Formisano, V. +2 more

This paper describes one of the sources of the data concerning the thermal structure of the Martian atmosphere, based on the thermal IR spectrometry method. It allows to investigate the Martian atmosphere below 55 km by retrieving the temperature profiles from the 15 µm CO₂ band. This approach enables to reach the vertical resolut…
