متن کاملVenus Cloud Properties from Venus Express VIRTIS Observations
Near-infrared spectra from the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) on Venus Express have been used to investigate the vertical structure and global distribution of cloud properties on Venus. The spectral range covered by VIRTIS is sensitive on the nightside to absorption by the lower and middle cloud layers, which are back-lit by radiation from the lower atmosphere and su...
متن کاملVenus Surface Thermal Emission Observed by VIRTIS on Venus Express
The imaging spectrometer VIRTIS is the flight spare of the instrument of the same name on the Rosetta mission. It was refitted to be part of the Venus Express mission orbiting Venus since 2006. VIRTIS can observe nightside thermal emissions at the wavelengths of several atmospheric windows. In three of these windows atmospheric transparency is sufficient to allow a measurable amount of radiatio...
متن کاملTropospheric carbon monoxide concentrations and variability on Venus from Venus Express/VIRTIS-M observations
[1] We present nightside observations of tropospheric carbon monoxide in the southern hemisphere near the 35 km height level, the first from Venus Express/Visible and Infrared Thermal Imaging Spectrometer (VIRTIS)-M-IR. VIRTIS-M data from 2.18 to 2.50 mm, with a spectral resolution of 10 nm, were used in the analysis. Spectra were binned, with widths ranging from 5 to 30 spatial pixels, to incr...
متن کاملDynamics of the Venus upper atmosphere: Outstanding problems and new constraints expected from Venus Express
A consistent picture of the dynamics of the Venus upper atmosphere from 90 to 200 km has begun to emerge [e.g., Bougher, S.W., Alexander, M.J., Mayr, H.G., 1997. Upper Atmosphere Dynamics: Global Circulation and Gravity Waves. Venus II, CH. 2.4. University of Arizona Press, Tucson, pp. 259–292; Lellouch, E., Clancy, T., Crisp, D., Kliore, A., Titov, D., Bougher, S.W., 1997. Monitoring of Mesosp...
