We report a previously unnoticed annually repeating phenomenon consisting of the daily formation of an extremely elongated cloud extending as far as 1,800 km westward from Arsia Mons. It takes place in the solar longitude (Ls) range of ∼220°–320°, around the Southern solstice. We study this Arsia Mons Elongated Cloud (AMEC) using images from different orbiters, including ESA Mars Express, NASA MAVEN, Viking 2, MRO, and ISRO Mars Orbiter Mission (MOM). We study the AMEC in detail in Martian year… 

A Long‐Term Study of Mars Mesospheric Clouds Seen at Twilight Based on Mars Express VMC Images

We present the first systematic study of clouds observed during twilight on Mars. We analyze images obtained by the Visual Monitoring Camera on Mars Express between 2007 and 2020. Using an automated

Evaluation of the Capability of ExoMars-TGO NOMAD Infrared Nadir Channel for Water Ice Clouds Detection on Mars

As part of the payload of the 2016 ExoMars Trace Gas Orbiter (TGO) mission, the Nadir and Occultation for MArs Discovery (NOMAD) suite instrument has been observing the Martian atmosphere since March

From engineering to science: Mars Express Visual Monitoring Camera's first science data release

This paper aims to provide a history of space exploration in the post-Soviet period from 1989 to 2002, using satellite imagery acquired during that period as a model for the construction of the International Space Station.

Martian limb-viewing clouds: A study based on MCC, MCS and MARCI observations



Some diurnal properties of clouds over the martian volcanoes

Discrete white cloud systems have long been recognized as a martian atmospheric phenomenon. However, it was not until the Mariner 9 mission in 1971–72 that the cloud systems were found to be closely

A Seasonally Recurrent Annular Cyclone in Mars Northern Latitudes and Observations of a Companion Vortex

We study a seasonally recurrent cyclone and related cloud phenomena observed on Mars at Ls ~120°, latitude ~60°N, and longitude 90°W from images obtained with cameras in different spacecraft between

Interannual variability of water ice clouds over major martian volcanoes observed by MOC

MOC observations of the 2001 Mars planet-encircling dust storm

Simulation of the atmospheric thermal circulation of a martian volcano using a mesoscale numerical model

This simulation of the mesoscale spiral dust cloud observed over the caldera of the volcano Arsia Mons is simulated by using the Mars Regional Atmospheric Modelling System, and reveals that the dust cloud is an indicator of a greater but optically thin thermal circulation that reaches heights of up to 30 km, and transports dust horizontally over thousands of kilometres.

The Onset and Growth of the 2018 Martian Global Dust Storm

We analyze the onset and initial expansion of the 2018 Martian Global Dust Storm (GDS 2018) using ground‐based images in the visual range. This is the first case of a confirmed GDS initiating in the

Martian Clouds Observed by Mars Global Surveyor Mars Orbiter Camera from Ls 135 to 310

We have made daily global maps that cover both polar and equatorial regions of Mars for Ls 135°–360° and 0°–111° using the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red and blue wide-angle

Observational consequences of Martian wind regimes

Observations of the initiation and evolution of the 2001 Mars global dust storm

[1] A global dust storm occurred on Mars between June and October 2001. The storm began near Hellas just before southern spring equinox (∼Ls = 177°). Local storms, likely forced by a combination of
