Dust Storm‐Enhanced Gravity Wave Activity in the Martian Thermosphere Observed by MAVEN and Implication for Atmospheric Escape [PDF]

Geophysical Research Letters, 2021
AbstractLower 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 on board NASA's Mars Atmosphere Volatile EvolutioN (MAVEN) spacecraft show a remarkable increase of gravity wave (GW)‐induced ...

Temporal characterization of sand and dust storm activity and its climatic and terrestrial drivers in the Aral Sea region

Atmospheric Research, 2022
As the Aral Sea shrinks, the lakebeds are gradually drying up, and the newborn Aralkum Desert (AD) has become one of the most active sands and dust storms (SDS) sources in Arid Central Asia (ACA). However, the temporal characterization of SDS activity and its possible driving factors have yet to be thoroughly investigated. Here, we studied the temporal

Secular Changes in Atmospheric Turbidity over Iraq and a Possible Link to Military Activity

Remote Sensing, 2020
We examine satellite-derived aerosol optical depth (AOD) data during the period 2000–2018 over the Middle East to evaluate the contribution of anthropogenic pollution. We focus on Iraq, where US troops were present for nearly nine years.

Godzilla mineral dust and La Soufrière volcanic ash fallout immediately stimulate marine microbial phosphate uptake

Frontiers in Marine Science
During the “Godzilla” dust storm of June 2020, unusually high fluxes of mineral dust traveled across the Atlantic from the Sahara Desert, reaching the Caribbean Basin, Gulf Coast, and southeastern United States.

Forecasting the Impact of Climatic Factors on Sand Dune Mobility in the Salt Lake Basin using Sensitivity Analysis. [PDF]

Desert
Due to its location in in the arid and semi-arid region of central Iran, The Salt Lake basin is constantly affected by erosive winds leading to the transportation and deposition of sediments.

The Mars Global Dust Storm of 2018 [PDF]

Mars is a dusty planet. Wind often lifts dust from the surface into the air forming clouds of dust at different locations across Mars. These dust storms typically last up to a couple days and grow to a few hundred km in size.

Comparison of Dust Storm Events between East Asia and North America [PDF]

E3S Web of Conferences
In this study, the decadal variations of global dust storm events (DSEs) are studied based on two typical cases that occurred in East Asia in 2023 and in North America in 1934, respectively.

Assessing the Radioactivity of Samples Taken during a Dust Storm in the Iraqi City of Hilla

Al-Kitab Journal for Pure Sciences
The research aims to investigate the distinguishing behaviors and risk indicators in samples of dust storms in Hilla city, Iraq. NaI (Tl) detector was used for the measurements, along with spectrum analysis.

Electrostatic fields in a dusty Martian environment [PDF]

While there have been several studies suggesting the possibility of electrical activity on Mars, to date there have been no measurements to search for evidence of such activity.

The impact of dry atmospheric deposition on the sea-surface microlayer and the sub-surface layer in the SE Mediterranean Sea: an experimental approach

Frontiers in Marine Science, 2016
The oligotrophic southeastern Mediterranean Sea (SEMS) is frequently exposed to desert-dust deposition which supplies nutrients, trace metals and a wide array of viable airborne microorganisms.
