Venus crater-related radar-dark parabolas and neighboring terrains: A comparison of 1-µm emissivity and microwave properties
Basilevsky, A. T.; Markiewicz, W. J.; Shalygin, E. V. +2 more
This work presents a comparative study of microwave properties and 1-µm emissivity for five Venus crater-associated radar-dark parabolas along with neighboring plains and some other geologic units. Craters of interest are Adivar, Bassi, Bathsheba, Sitwell, and du Chatelet with nearby crater Caccini having non-parabolic radar-dark halo. Micro…

Water vapor in the middle atmosphere of Mars during the 2007 global dust storm
Montmessin, Franck; Bertaux, Jean-Loup; Korablev, Oleg +4 more
Recent observations of the Martian hydrogen corona in the UV H Ly-alpha emission by the Hubble Space Telescope (HST) (Clarke et al., 2014) and the SPICAM UV spectrometer on Mars Express (Chaffin et al., 2014) reported its rapid change by an order of magnitude over a short few months period in 2007 (MY28), which is inconsistent with the existing mo…
Equatorial locations of water on Mars: Improved resolution maps based on Mars Odyssey Neutron Spectrometer data
Elphic, Richard C.; Massey, Richard J.; Maurice, Sylvestre +4 more
We present a map of the near subsurface hydrogen distribution on Mars, based on epithermal neutron data from the Mars Odyssey Neutron Spectrometer. The map's spatial resolution is approximately improved two-fold via a new form of the pixon image reconstruction technique. We discover hydrogen-rich mineralogy far from the poles, including ∼10 wt.% w…
The GEM-Mars general circulation model for Mars: Description and evaluation
Daerden, F.; Neary, L.
GEM-Mars is a gridpoint-based three-dimensional general circulation model (GCM) of the Mars atmosphere extending from the surface to approximately 150 km based on the GEM (Global Environmental Multiscale) model, part of the operational weather forecasting and data assimilation system for Canada. After the initial modification for Mars, the model h…
Atmospheric structure and helium abundance on Saturn from Cassini/UVIS and CIRS observations
Guerlet, S.; Koskinen, T. T.
We combine measurements from stellar occultations observed by the Cassini Ultraviolet Imaging Spectrograph (UVIS) and limb scans observed by the Composite Infrared Spectrometer (CIRS) to create empirical atmospheric structure models for Saturn corresponding to the locations probed by the occultations. The results cover multiple locations at low to…
Study of Titan's fall southern stratospheric polar cloud composition with Cassini/CIRS: Detection of benzene ice
de Kok, R.; Flasar, F. M.; Bézard, B. +5 more
We report the detection of a spectral signature observed at 682 cm-1 by the Cassini Composite Infrared Spectrometer (CIRS) in nadir and limb geometry observations of Titan's southern stratospheric polar region in the middle of southern fall, while stratospheric temperatures are the coldest since the beginning of the Cassini mission.
