Identification and Quantification of Aerosol Hot-spots over Lahore Region using MODIS Data [PDF]
arXiv, 2020 The increased concentration of aerosols in the air caused by ever-rising urbanization and the development of various industries has horrendous consequences on human health, environment and climate. The first step to counter adverse effects of air pollution in any region is to identify locations with a high concentration of aerosols, termed aerosol hot ...

Post-corona unipolar chargers with tuneable aerosol size-charge relations: Parameters affecting ion dispersion and particle trajectories for charger designs [PDF]
, 2020 This paper focusses on the mean charge per particle of monodisperse submicron aerosol, charged by diffusion of unipolar ions in post-corona discharge. It aims to confirm and discuss the limits of considering a single value of Ni$\times$t to describe aerosol charging and then to present methods to control the size-charge relation. Three aerosol chargers,

Long-range Transport of Air Pollutants to Taiwan during the COVID-19 Lockdown in Hubei Province
Aerosol and Air Quality Research, 2020 Lockdown implemented to limit transmission of the COVID-19 virus in China reduced the emissions of air pollutants especially around Hubei Province, though restrictions were more widely applied across the country.

CFD modeling of a vehicle exhaust laboratory sampling system: sulfur-driven nucleation and growth in diluting diesel exhaust [PDF]
Atmospheric Chemistry and Physics, 2015 A new exhaust aerosol model CFD-TUTEAM (Tampere University of Technology Exhaust Aerosol Model for Computational Fluid Dynamics) was developed. It is based on modal aerosol dynamics modeling with log-normal assumption of particle distributions. The model

In situ characterization of mixed phase clouds using the Small Ice Detector and the Particle Phase Discriminator [PDF]
Atmospheric Measurement Techniques, 2016 Mixed phase clouds (MPCs) represent a great source of uncertainty for both climate predictions and weather forecasts. In particular, there is still a lack of understanding on how ice forms in these clouds.

Effective radiative forcing in the aerosol-climate model CAM5.3-MARC-ARG [PDF]
Atmos. Chem. Phys. Discuss., https://doi.org/10.5194/acp-2018-118,
in review, 2018 We quantify the effective radiative forcing (ERF) of anthropogenic aerosols modelled by the aerosol-climate model CAM5.3-MARC-ARG. CAM5.3-MARC-ARG is a new configuration of the Community Atmosphere Model version 5.3 (CAM5.3) in which the default aerosol module has been replaced by the two-Moment, Multi-Modal, Mixing-state-resolving Aerosol model for ...

Aerosol Transmission of Filoviruses [PDF]
Viruses, 2016 Filoviruses have become a worldwide public health concern because of their potential for introductions into non-endemic countries through international travel and the international transport of infected animals or animal products. Since it was first identified in 1976, in the Democratic Republic of Congo (formerly Zaire) and Sudan, the 2013–2015 ...

Aerosol Characteristics at a High Altitude Location in Central Himalayas: Optical Properties and Radiative Forcing [PDF]
, 2006 Collocated measurements of the mass concentrations of aerosol black carbon (BC) and composite aerosols near the surface were carried out along with spectral aerosol optical depths (AODs) from a high altitude station, Manora Peak in Central Himalayas, during a comprehensive aerosol field campaign in December 2004.
