Abstract

International audience; We present vertical profiles of water ice clouds in the Martian atmosphere, and the effects of the last global dust storm on them. To this end, we used the data produced by the ACS MIR channel during solar occultations that senses the atmospheric opacity in the 3 μm spectral range. We observe very rapidchanges in the aerosol profile associated with the onset of the global dust event, initiating water ice cloud layer formation above 80 km in a period of days or so, sug- gesting a sudden intensification in the circulation re- gime. More work is needed to extract more infor- mation, such as particle size, yet this preliminary study already provides some insightful data about water ice during the 2018 global dust storm.

Abstract

International audience; The Atmospheric Chemistry Suite (ACS), one of four science experiments on board ESA-Roscosmos ExoMars 2016 Trace Gas Orbiter (TGO) mission has started science operations in March 2018. ACS consists of three infrared spectrometers targeting the unambiguous detection of trace gases of potential geophysical or biological interest. ACS channels feature very high accuracy (ppt level), very high resolving power (>10,000) and broad spectral coverage (0.7 to 17 μm). The near-infrared (NIR) channel covers the 0.7-1.6 μm spectral range with a resolving power of ≥20,000. This channel is operated in solar occultation and nadir. In nadir NIR is mostly measuring water vapor and dayside oxygen emission. In solar occultation NIR demonstrates profiling of CO2, H2O with high accuracy and in a broad altitude range, and also the molecular oxygen O2, the first ever profiling in the lower atmosphere. NIR observes occultations together with the two other ACS channels MIR and TIRVIM, either together with another spectrometer aboard TGO, NOMAD, and TIRVIM. The mid-infrared (MIR) channel is a high spectral resolution (resolving power of 50,000) instrument dedicated to solar occultation measurements in the 2.2-4.4 μm range. MIR is conceived to accomplish the most sensitive measurements of the trace gases in the Martian atmosphere, allowing also parallel profiling of the abundant components such as CO2, H2O and their isotopologues. The thermal-infrared channel (TIRVIM) is a Fourier-transform spectrometer with cryogenically-cooled detector encompassing the spectral range of 1.7-17 μm. Observing the CO2 15-µm band in nadir TIRVIM returns temperature profiles from the surface up to 50-60 km, together with the dust and water ice optical depth. Also the surface temperature is measured. In solar occultation TIRVIM delivers profiles of CO2, CO, H2O and aerosols, as well allowing to distinguish between mineral and condensate aerosols. ACS has monitored the state of the martian atmosphere before and during the dust event 2018A. The status of the experiment and key findings available by the time of the conference will be reported.

Abstract

International audience; The NOMAD spectrometer suite on the ExoMars Trace Gas Orbiter will map the composition and distribution of Mars' atmospheric trace species in unprecedented detail, fulfilling many of the scientific objectives of the joint ESA-Roscosmos ExoMars Trace Gas Orbiter mission. The instrument is a combination of three channels, covering a spectral range from the UV to the IR, and can perform solar occultation, nadir and limb observations. In this paper, we present the science objectives of the instrument and how these objectives have influenced the design of the channels. We also discuss the expected performance of the instrument in terms of coverage and detection sensitivity.

Abstract

Venus has no seasons, slow rotation and a very massive atmosphere, which is mainly carbon dioxide with clouds primarily of sulphuric acid droplets. Infrared observations by previous missions to Venus revealed a bright 'dipole' feature surrounded by a cold 'collar' at its north pole(1-4). The polar dipole is a 'double-eye' feature at the centre of a vast vortex that rotates around the pole, and is possibly associated with rapid downwelling. The polar cold collar is a wide, shallow river of cold air that circulates around the polar vortex. One outstanding question has been whether the global circulation was symmetric, such that a dipole feature existed at the south pole. Here we report observations of Venus' south-polar region, where we have seen clouds with morphology much like those around the north pole, but rotating somewhat faster than the northern dipole. The vortex may extend down to the lower cloud layers that lie at about 50 km height and perhaps deeper. The spectroscopic properties of the clouds around the south pole are compatible with a sulphuric acid composition.

Abstract

International audience; The Planetary Fourier Spectrometer (PFS) for the Mars Express mission is an infrared spectrometer optimised for atmospheric studies. This instrument has a short wave (SW) channel that covers the spectral range from 1700 to 8200.0cm-1 (1.2- 5.5mum) and a long-wave (LW) channel that covers 250- 1700cm-1 (5.5- 45mum). Both channels have a uniform spectral resolution of 1.3cm-1. The instrument field of view FOV is about 1.6o (FWHM) for the Short Wavelength channel (SW) and 2.8o (FWHM) for the Long Wavelength channel (LW) which corresponds to a spatial resolution of 7 and 12 km when Mars is observed from an height of 250 km. PFS can provide unique data necessary to improve our knowledge not only of the atmosphere properties but also about mineralogical composition of the surface and the surface-atmosphere interaction. The SW channel uses a PbSe detector cooled to 200-220 K while the LW channel is based on a pyroelectric ( LiTaO3) detector working at room temperature. The intensity of the interferogram is measured every 150 nm of physical mirrors displacement, corresponding to 600 nm optical path difference, by using a laser diode monochromatic light interferogram (a sine wave), whose zero crossings control the double pendulum motion. PFS works primarily around the pericentre of the orbit, only occasionally observing Mars from large distances. Each measurements take 4 s, with a repetition time of 8.5 s. By working roughly 0.6 h around pericentre, a total of 330 measurements per orbit will be acquired 270 looking at Mars and 60 for calibrations. PFS is able to take measurements at all local times, facilitating the retrieval of surface temperatures and atmospheric vertical temperature profiles on both the day and the night side.
