The Atmospheric Chemistry Suite (ACS) package is an element of the Russian contribution to ESA-Roscosmos ExoMars 2016 Trace Gas Orbiter (TGO) mission. ACS consists three separate infrared spectrometers, sharing common mechanical, electrical, and thermal interfaces. This ensemble spectrometers has been designed developed in response mission objectives that specifically address requirement high sensitivity instruments enable unambiguous detection trace gases potential geophysical or biological...
Abstract Based on the analysis of UV images (at 365 nm) Venus cloud top (altitude 67 ± 2 km) collected with Monitoring Camera board Express (VEX), it is found that zonal wind speed south equator (from 5°S to 15°S) shows a conspicuous variation −101 −83 m/s) geographic longitude Venus, correlated underlying relief Aphrodite Terra. We interpret this pattern as result stationary gravity waves produced at ground level by uplift air when horizontal encounters mountain slope. These can propagate...
To date dynamical observations of the Venus clouds have delivered mainly either only short‐term or long‐term averaged results. With Monitoring Camera (VMC) it finally became possible to investigate global dynamics with a relatively high resolution in space and time on basis. Our findings from manual cloud feature wind tracking VMC UV image sequences so far show that details mesospheric appear be highly variable. Although general rotation atmosphere remained stable since Mariner 10, more than...
Abstract For more than 8 years the Venus Monitoring Camera (VMC) onboard Express orbiter performed continuous imaging of cloud layer in UV, visible and near‐IR filters. We applied correlation approach to sequences images at 965 nm track features determine wind field middle lower (49–57 km). From VMC that spanned from December 2006 through August 2013 we derived zonal meridional components field. In low‐to‐middle latitudes (5–65°S) velocity retrograde was found be 68–70 m/s. The slowly...
Images obtained by the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS)‐M channel instrument onboard Venus Express have been used to retrieve maps apparent motions of O 2 ( 1 Δ) infrared nightglow on at 1.27 μ m. The distribution is highly inhomogeneous with regions brightest emission generally located low latitudes near midnight meridian. Unexpectedly some orbits show also intense airglow activity over south polar region. spatially resolved spectacularly variable not only in its...

We investigate nature of UV exhibited by examining possible correlations between thermal structure inferred from radio occultation data brightness imagery data, both observed with Express. analyse Express images obtained 11 hours before a few after time measurements same area. account for advection zonal meridional winds...

Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) onboard the Venus Express spacecraft has been operating since April 2006 providing new observations of temperature structure mesosphere (60–95 km). Zonal winds in middle atmosphere have retrieved from VIRTIS profiles using cyclostrophic approximation. The wind field is characterized by three main features: (1) a midlatitude jet connected to thermal feature known as cold collar; reaches maximum speed 80–90 ± 10 m/s near cloud top (∼70...
Abstract The paper is devoted to the investigation of Venus mesosphere circulation at 90–110 km altitudes, where tracking O 2 (a 1 Δ g ) 1.27 μm nightglow practically only method studying circulation. images were obtained by VIRTIS‐M on Express over course more than years. resulting global mean velocity vector field covers nightside between latitudes 75°S–20°N and local time 19–5 h. main observed mode two opposite flows from terminators midnight; however, wind speed in eastward direction...
We present joint analysis of the UV (365 nm) images captured by cameras on board ESA’s Venus Express and JAXA’s Akatsuki spacecraft. These observations enabled almost continuous characterization cloud top circulation over longest period time so far (2006–2021). More than 46,000 wind vectors were derived from tracking features revealed changes in atmospheric with 12.5 ± 0.5 years. The zonal component is characterized an annual mean −98.6 1.3 m/s amplitude 10.0 1.6 m/s. meridional velocity...
