Venus 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...

Cloud Structure on Venus with VIRTIS

Near-infrared spectra from the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) on Venus Express provide the opportunity for investigating and constraining a wide range of atmospheric parameters for Venus. The aim of this work is to exploit the wealth of data available from Venus Express to better understand the behaviour of the Venusian clouds, which are known to play a significant r...

A bulk cloud parameterization in a Venus General Circulation Model

A condensing cloud parameterization is included in a super-rotating Venus General Circulation Model. A parameterization including condensation, evaporation and sedimentation of mono-modal sulfuric acid cloud particles is described. Saturation vapor pressure of sulfuric acid vapor is used to determine cloud formation through instantaneous condensation and destruction through evaporation, while p...
