Abstract. The chemical and morphological properties of mineral dust aerosols emitted by wind erosion from arid semi-arid regions influence climate, ocean, land ecosystems; air quality; multiple socio-economic sectors. However, there is an incomplete understanding the particle size distribution (PSD) in terms its constituent minerals that typically result fragmentation soil aggregates during erosion. PSD affects duration transport thus each mineral's global distribution, along with specific...

Vertical help understand behaviour temperature inversion, their relationship each other. tethered balloon equipped with in-situ instruments measure Particulate Matter (PM),...
Abstract. Iceland is a major high-latitude dust source area. Airborne Icelandic influences the climate system via interacting with radiation, clouds, and biogeochemical systems, impacts snow/ice albedo, air quality. These are sensitive to its mineralogical, chemical, physical composition. However, comprehensive particle measurement analysis of still limited. This study examines samples collected during field campaign in Dyngjusandur desert (August–September 2021) using active passive aerosol...
Mineral dust is one of the key players in Earth’s atmosphere with respect to climate and atmospheric nutrient transport. Dust spans a large size range particle diameters, reaching from around 100 nm more than µm. While it has been assumed for long time that super-coarse (10 - 62.5 µm) giant (> particles are not widely dispersed sources, recent observations show they can travel on regional up even intercontinental scale. Owing negligence difficulty measurement,...
Mineral dust is one of the most prominent natural aerosols and almost ubiquitous in atmosphere, where it substantially interacts, modulates alter atmospheric processes. Although research on aerosol carried out since many decades by means different approaches techniques, knowledge mineral emitted at high latitudes or cold climate regions still limited despite its pivotal impact polar environments. Within a warming climate, from sources located zones expected to increase due retreat ice sheets...
Mineral dust is one of the most abundant types aerosol particles in atmosphere, playing a crucial role various atmospheric processes. A key interaction within clouds its ability to produce ice-nucleating (INPs), influencing cloud properties such as phase, lifetime, and water content. The efficiency mineral INPs depends on factors mineralogy, composition, particle size. This study investigates size mineralogy INP efficiency, contrasting Morocco Iceland, i.e. mid- high-latitude sources by...
With the decrease of electronic component prices, powerful yet low-cost optical particle counters (OPCs) gain in popularity and are frequently used citizen science as well classical projects. The application OPCs large numbers can yield higher spatial resolution and, thus, offers great opportunities for studies distribution development, e.g. dust or air pollution. As a consequence, sensor performance long-term accuracy must be evaluated order maintain data quality.During HiLDA campaign,...
Abstract. Characterising the physico-chemical properties of dust-emitting sediments in arid regions is fundamental to understanding effects dust on climate and ecosystems. However, knowledge regarding high-latitude (HLD) remains limited. This study focuses analysing particle size distribution (PSD), mineralogy, cohesion, iron (Fe) mode occurrence, visible–near infrared (VNIR) reflectance spectra from hotspots Iceland (HLD region). Extensive analysis was conducted samples top sediments,...
Abstract. Mineral dust effects upon climate are strongly affected by its particle size distribution (PSD). In particular, the emitted PSD partly controls lifetime and global distribution. Despite extensive research performed on this topic over last decades, there still substantial gaps in our understanding of along with potential variability associated causes. study, we provide insights into saltation size-resolved emission process based measurements obtained during a comprehensive wind...

Abstract. Constraining dust models to understand and quantify the effect of upon climate ecosystems requires comprehensive analyses physiochemical properties dust-emitting sediments in arid regions. Building previous studies Moroccan Sahara Iceland, we analyse a diverse set crusts aeolian ripples (n=55) from various potential basins within Mojave Desert, California, USA. Our focus is on characterizing particle size distribution (PSD), mineralogy, aggregation/cohesion state, Fe mode...

Abstract. The effects of desert dust upon climate and ecosystems depend strongly on its particle size size-resolved mineralogical composition. However, there is very limited quantitative knowledge the composition parent sediments along with their variability within dust-source regions, particularly in emission hotspots. lower Drâa Valley, an inland drainage basin hotspot region located Moroccan Sahara, was chosen for a comprehensive analysis sediment mineralogy.
