Temporal and Geographical Variation in Martian Surface Dust Lifting Processes
… the variability of key aspects of the Martian dust cycle and investigating their importance in predicting conditions for spacecraft atmospheric descent and landing. The dust cycle – lifting, transportation and deposition – is a significant Martian climate cycle. The geographical and temporal …

Fully kinetic particle-in-cell simulations of plasma-surface-dust interactions for lunar exploration
<p>"The studies involving lunar surface explorations have drawn attentions in recent years. A better understanding of possible potential hazards to astronauts and electronic equipment has become a necessity for future lunar explorations. The lunar surface, lacking an atmosphere and global magnetic …

Decoupling of iron and phosphate in the global ocean
… between Fe and P04 and the sensitivity of surface nutrient concentrations to changes in aeolian iron supply, I use a hierarchy of ocean circulation and biogeochemistry models. I formulate a mechanistic model of iron cycling which includes scavenging onto sinking particles and complexation …

Simulating and quantifying land-surface biogeochemical, hydrological, and biogeophysical processes using the Community Land Model version 4
… variations. Last but not least, mineral dust, a type of atmospheric aerosol, alters surface radiation/energy balance, and may act as cloud condensation nuclei to modify precipitation rates and eventually the hydrological cycle. Therefore, we were motivated to investigate these processes …

Detection and Characterisation of Airborne Carcinogenic Erionite Fibres in New Zealand Roadside Environments Using a Novel Integrated Methodology
Geogenic airborne dust is a common phenomenon in both urban construction zones and rural roadside environments, particularly where sediment layers are exposed and disturbed. In regions with volcaniclastic geology, such dust may contain naturally occurring carcinogenic minerals, including fibrous …

Evaluating different remote sensing techniques for detection of Saharan dust and characterisation of dust sources
Mineral dust aerosols play an important role in climate and the Earth's energy budget. However, the nature and complexity of dust sources is poorly understood. Traditional techniques used for mapping the Sahara dust sources like the analysis of surface dust observations, back trajectory analysis of …
