Dust, Sand, and Winds Within an Active Martian Storm in Jezero Crater

Geophysical Research Letters, 2022
Abstract Rovers and landers on Mars have experienced local, regional, and planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive. Over 5–11 January 2022 (L S 153°–156°), a dust storm passed over the Perseverance rover

Evaluation and Analysis of Dust Storm Activity in Tianwen-1 Landing Area Based on the Moderate Resolution Imaging Camera Observations and Mars Daily Global Maps

Remote Sensing, 2021
The first Mars exploration mission from China (Tianwen-1) was launched on 23 July 2020 with the goal of “orbiting, landing, and roving”. The occurrence of dust storm activities is an important criterion of assessing atmospheric risk for the Tianwen-1 ...

Evaluation of Heavy Metals Concentration in Street, Storm and Suspended Dust in Al-Zafaraniya Area, Baghdad- Iraq

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023
The current study was applied in Al-Zafaraniya area southeast of the capital Baghdad from October 2021 to April 2022. This is to evaluate some heavy elements (Cd, Co, Cu, Fe, Pb, and Mn) in the street, storm, and suspended dust.

Detecting electrical activity from Martian dust storms [PDF]

Journal of Geophysical Research: Planets, 1999
We present a model addressing the possible electrification of Martian dust storms based on the effective electrical charging of an individual dust grain. An upper charge bound on a grain can be determined based on the grain capacitance in the low‐pressure Martian atmosphere.

Observational evidence for active dust storms on Titan at equinox [PDF]

Nature Geoscience, 2018
Saturn’s moon Titan has a dense nitrogen-rich atmosphere, with methane as its primary volatile. Titan’s atmosphere experiences an active chemistry that produces a haze of organic aerosols that settle to the surface and a dynamic climate in which hydrocarbons are cycled between clouds, rain and seas.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

Geodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Spatial mapping of the provenance of storm dust: Application of data mining and ensemble modelling [PDF]

, 2020
Spatial modelling of storm dust provenance is essential to mitigate its on-site and off-site effects in the arid and semi-arid environments of the world.

Dust storm-enhanced gravity wave activity in the Martian thermosphere observed by MAVEN and implications for atmospheric escape [PDF]

Geophysical Research Letters, 2020
Lower atmospheric global dust storms affect the small- and large-scale weather and variability of the whole Martian atmosphere. Analysis of the CO2 density data from the Neutral Gas and Ion Mass Spectrometer instrument (NGIMS) on board NASA’s Mars Atmosphere Volatile EvolutioN (MAVEN) spacecraft show a remarkable increase of GW-induced density ...
