Characterization and analysis of the ambient aerosol species in the Shenandoah National Park and Manassas, Virginia regions
… composition and elemental concentration of the aerosol species in the Shenandoah National Park and Manassas, Virginia regions was investigated during a three month summertime period. The relationships between the above mentioned parameters along with prevalent meteorological patterns, emission …

Impact of Saharan Dust as CCN on the Evolution of an Idealized Tropical Cyclone
… nature of the interaction between nucleating aerosols and TC dynamics are inseparable, which makes the ultimate impact of the ambient aerosol concentration on the TC intensity difficult to predict.

Physical and Chemical Properties of Laboratory and Ambient Aerosols Related to Climate Change
… of closure when measuring and modeling aerosol optical properties as a function of RH in a laboratory and reports measured ambient aerosol optical and chemical properties for an anthropogenically perturbed continental US site from 1995 to 2000. The optical closure experiment was …

Investigating the Molecular Composition of Rainwater and Secondary Organic Aerosol using Ultra-High Resolution Mass Spectrometry
… complete molecular characterisation of organic aerosol. However atmospheric aerosol often has complex, mixed organic and inorganic composition and soft ionisation techniques that have been developed to ionise organic aerosol specifically, are susceptible to salt suppression effects and …

Iron Reduction in Soot
… generation of reactive oxygen species (ROS) from ambient particles emitted during the incomplete combustion of fossil and biomass fuels. Although ROS are known to induce unhealthy oxidative stress in cellular systems, the mechanisms of Fe(II) formation and stabilization in aerosol particles are …

Isolation of ambient aerosols of known critical supersaturation: the differential critical supersaturation separator (DSCS)
… has been developed that isolates from an ambient aerosol population only those particles that have critical supersaturations, Sc, within a narrow, user-specified, range. This Differential Critical Supersaturation Separator (DScS) is designed to supply one or more particle size and/or …

The application of low-cost sensors to monitor and characterise particulate matter air pollution
… and how these may vary under typical ambient conditions. Low-cost sensors can improve the spatial resolution and range of deployment sites of particle measurements as they are cheaper to buy and run, and require less space, energy and specialist skills to operate. However, their scope …

Investigating the potential of meltwater as a local source of ice nucleating particles in the central Arctic summer
… is a unique period characterized by pristine aerosol conditions, in which emissions from local sources have an increased influence, potentially impacting the ubiquitous low-lying AMPCs. Thus, the summer is an ideal season for exploration of the potential importance of INPs from local sources, …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… of environmental pollutants in the context of ambient air, indoors, as well as in working environments. Sampling, extraction, sample clean up and analysis constitute the principal stages required for the determination of airborne PAHs. Most conventional methods utilize high volume samplers and …
