International audience ; The Imaging Ultraviolet Spectrograph (IUVS) instrument on the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft takes mid-UV spectral images of the Martian surface and atmosphere. From these apoapse images, a variety of cloud morphologies and local time variability can be seen and comprise the only MAVEN observations of water ice aerosols. Measuring local time variability of large-scale recurring cloud features is made possible with MAVEN's 4.5-hour elliptical orbit, something not possible with sun-synchronous orbits. We have examined two Martian years' worth of data and present an overview of IUVS cloud observations. Topographic clouds are one of the most visually striking types of clouds observed in our data, which are seen throughout northern hemisphere summer (Ls = 90°) and persist into northern fall (Ls = 180°). These clouds are generally localized to Tharsis volcanoes and show streaks, waves, and spirals. From northern spring into late summer we also see the presence of aphelion cloud belt (ACB) clouds, a longitudinally continuous band of clouds that forms near equatorial regions. Throughout the year we see the presence of polar hoods. Sometimes these clouds are simply an amorphous structure centered around the pole; other times we see the presence of single and double vortices as well as cyclonic features that appear and diminish on the timescale of several hours. Finally, we have observed clouds above the 2018 dust storm. Some clouds are wispy--reminiscent of cirrus clouds--while other times we see the presence of gravity waves in the clouds and a "terminator cloud band." We present observations of these cloud morphologies and preliminary retrievals of aerosol properties. |
