Efficient Modeling of Particle Transport through Aerosols in GEANT4 [PDF]
We present a geometry class for efficiently simulating particle transport through aerosols in GEANT4. It is demonstrated that aerosol granularity can strongly affect this transport and thus a generic aerosol model must respect this granularity, which the presented class achieves by modelling the aerosol as a collection of droplets.

Aerosols in the mortuary. [PDF]
Air counts in seven mortuaries during necropsies revealed that providing care is taken with washing intestines and close dissection, bacterial numbers are often less than those found in an operating theatre, and relate more to the number of people and movement in the room than the work.

Reconstruction of Refractive Indices from Spectral Measurements of Monodisperse Aerosols [PDF]
For the investigation of two-component aerosols one needs to know the refractive indices of the two aerosol components. One problem is that they depend on temparature and pressure, so one needs for their determination a robust measurement instrument such as the FASP device, which can cope with rigid environmental conditions.

Refined Source Apportionment of Atmospheric PM2.5 in a Typical City in Northwest China
The Xixian New District (XXND), established in 2014, is the seventh national-level new district in China, but research on air pollution there has been limited. This study focused on the characteristics and sources of PM2.5 in XXND from 2017 to 2018.

Stratospheric Albedo Modification by Aerosol Injection [PDF]
This paper reviews and develops the proposal, widely discussed but not examined in detail, to use stratospheric aerosols to increase the Earth's albedo to Solar radiation in order to control climate change. The potential of this method has been demonstrated by the "natural experiments" of volcanic injection of sulfate aerosols into the stratosphere ...

Diffuse fraction as a tool for exploring the sensitivity of parametric clear-sky models to changing aerosol conditions [PDF]
Aerosols' impact on the performance of a clear-sky solar irradiance model is often evaluated from the perspective of the overall accuracy of estimates. This study assesses the aerosol role in clear-sky solar irradiance modelling from a totally different perspective, namely the ability of a model to accurately separate global solar irradiance into its ...

Constraining the Atmospheric Composition of the Day-Night Terminators of HD 189733b : Atmospheric Retrieval with Aerosols [PDF]
A number of observations have shown that Rayleigh scattering by aerosols dominates the transmission spectrum of HD 189733b at wavelengths shortward of 1 $\mu$m. In this study, we retrieve a range of aerosol distributions consistent with transmission spectroscopy between 0.3-24 $\mu$m that were recently re-analyzed by Pont et al. (2013).

Review of Aerosol–Cloud Interactions: Mechanisms, Significance, and Challenges
Over the past decade, the number of studies that investigate aerosol–cloud interactions has increased considerably. Although tremendous progress has been made to improve the understanding of basic physical mechanisms of aerosol–cloud interactions and ...
