Abstract MRO-MARCI daily global mapping images from 16 November 2006 (Ls = 111.4°) through 15 July 2017 (Ls = 33.5°), covering portions of seven consecutive Martian years (MY 28 – MY 34), were used in a survey of dust storm activity within 2000 km radius of the final three candidate sites for the 2020 Mars Rover mission (Columbia Hills at 14.59° S ...

Magnetic storms during the space age: Occurrence and relation to varying solar activity [PDF]
We study the occurrence of magnetic storms in space age (1957-2021) using Dst and Dxt indices. We find 2526/2743 magnetic storms in the Dxt/Dst index, out of which 45% are weak, 40% moderate, 12% intense and 3% major storms. Occurrence of storms in space age follows the slow decrease of sunspot activity and the related change in solar magnetic ...

Rocket dust storms and detached dust layers in the Martian atmosphere [PDF]
Airborne dust is the main climatic agent in the Martian environment. Local dust storms play a key role in the dust cycle; yet their life cycle is poorly known. Here we use mesoscale modeling that includes the transport of radiatively active dust to predict the evolution of a local dust storm monitored by OMEGA on board Mars Express.

Diagnostic Study of a Severe Dust Storm over North Africa and the Arabian Peninsula
This work aimed to study the synoptic evolution and dynamics of the dust activity associated with the desert cyclone occurring over North Africa and the Arabian Peninsula on 4–8 April 2007 based on ECMWF analysis (ERA5) data.

Effects of Solar Activity, Solar Insolation and the Lower Atmospheric Dust on the Martian Thermosphere [PDF]
A diagnosis of the Ar densities measured by the Neutral Gas and Ion Mass Spectrometer aboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) and the temperatures derived from these densities shows that solar activity, solar insolation, and the lower atmospheric dust are the dominant forcings of the Martian thermosphere.

Based on a 39.8 m ice core drilled at the East Rongbuk Glacier (27°59′N, 86°55′E 6518 m a.s.l,), north slope of Mt. Qomolangma (Everest), central Himalaya, the changes of dust storm over the Tibetan Plateau (TP) recorded by insoluble particle and its possible connection with the winter (JFM) North Atlantic Oscillation (NAO) are investigated.

Dust storm is one of the main global challenges that is more serious in the Middle- East. This phenomenon causes a lot of environmental and socio- economic problems in Iran and several other Middle-Eastern countries. A Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used for trajectory analysis in order to reconstruct the ...

Recent activities for the dust storm studies in Central Asia
This paper provides an overview of state-of-the-art technologies used to detect and predict sand and dust storms (SDS). SDS events typically occur when strong winds transport dry sand and dust particles from the ground. Several technologies have been developed to detect and predict SDS, with the goal of mitigating their impact on the natural ...

Relationship between frontal dust storms and transient eddy activity in the northern hemisphere of Mars as observed by Mars Global Surveyor [PDF]
We have compiled a catalog of frontal dust storms in the northern hemisphere using Mars Orbiter Camera daily global maps spanning ∼2.3 Martian years of Mars Global Surveyor (MGS) observations (from 1999 to 2003). The most vigorous frontal storms that flush dust to the low latitudes occur in early‐mid fall and mid‐late winter, away from the northern ...
