Special Issue Information

Dear Colleagues,

Suspended particulate matter in the atmosphere, commonly known as atmospheric aerosols, is recognized as an important source of uncertainty in our understanding of processes ranging from local to global scales, and of issues addressed to both climate change and the environment. The scattering and absorption of solar and terrestrial radiation as direct aerosol effects, and the modification of cloud condensation nuclei through aerosol cloud interaction as indirect aerosol effects, leads to the largest uncertainty in assessing the radiative forcing. Both types, naturally occurring (e.g., dust, volcanic ash, pollen) and anthropogenic aerosols have well-known short-term and long-term detrimental effects on human health, causing respiratory problems, cardiovascular disease, and even premature death. Apart from human health effects, there are other open issues related to the environmental health and safety effects of atmospheric aerosols that require basic and fundamental studies that can help in explaining observed phenomena. Some of these include radioactive and heavy metal contamination as well as water supply and food contamination. The impact and safety concerns of aerosols with respect to aviation, roadway, railroad, and marine navigation are remaining challenges in the field of aerosol science. The role of aerosols in ice formation at high altitudes and reducing visibility in the lower troposphere are some examples of hazards impacting the key transportation infrastructures.

The goal of this Special Issue is to bring together scientists using remote sensing observation methods to monitor and numerically model and predict occurrences of various potential hazard phenomena caused by atmospheric aerosols.

Icelandic topsoil sediments, as confirmed by numerous scientific studies, represent the largest and the most important European source of mineral dust. Strong winds, connected with the intensive cyclonic circulation in the North Atlantic, induce intense emissions of mineral dust from local sources all year and carry away these fine aerosol particles for thousands of kilometers. Various impacts of airborne mineral dust particles on local air quality, human health, transportation, climate and marine ecosystems motivated us to design a fully dynamic coupled atmosphere–dust numerical modelling system in order to simulate, predict and quantify the Icelandic mineral dust process including: local measurements and source specification over Iceland. In this study, we used the Dust Regional Atmospheric Model (DREAM) with improved Icelandic high resolution dust source specification and implemented spatially variable particle size distribution, variable snow cover and soil wetness. Three case studies of intense short- and long-range transport were selected to evaluate the model performance. Results demonstrated the model’s capability to forecast major transport features, such as timing, and horizontal and vertical distribution of the processes. This modelling system can be used as an operational forecasting system, but also as a reliable tool for assessing climate and environmental Icelandic dust impacts. Full article

On 2 June 2014, at about 13 UTC, a dust storm arrived in Tehran as a severe hazard that caused injures, deaths, failures in power supply, and traffic disruption. Such an extreme event is not considered as common for the Tehran area, which has raised the question of the dust storm’s origin and the need for increasing citizens’ preparedness during such events. The analysis of the observational data and numerical simulations using coupled dust-atmospheric models showed that intensive convective activity occurred over the south and southwest of Tehran, which produced cold downdrafts and, consequently, high-velocity surface winds. Different dust source masks were used as an input for model hindcasts of the event (forecasts of the past event) to show the capability of the numerical models to perform high-quality forecasts in such events and to expand the knowledge on the storm’s formation and progression. In addition to the proven capability of the models, if engaged in operational use to contribute to the establishment of an early warning system for dust storms, another conclusion appeared as a highlight of this research: abandoned agricultural areas south of Tehran were responsible for over 50% of the airborne dust concentration within the dust storm that surged through Tehran. Such a dust source in the numerical simulation produced a PM10 surface dust concentration of several thousand μm/m3, which classifies it as a dust source hot-spot. The produced evidence indivisibly links issues of land degradation, extreme weather, environmental protection, and health and safety. Full article
