Synthesis of satellite (MODIS), aircraft (ICARTT), and surface (IMPROVE, EPA-AQS, AERONET) aerosol observations over eastern North America to improve MODIS aerosol retrievals and constrain surface aerosol concentrations and sources [PDF]

, 2010
We use an ensemble of satellite (MODIS), aircraft, and ground-based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new ...

Update on the Science and Technology of Diesel Particulate Filters

KONA Powder and Particle Journal, 2014
As diesel emission regulations become more stringent, diesel particulate filters (DPFs) have become possibly the most important and complex diesel emission control device. This paper provides an update on the science

An overview of the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) project: aerosol–cloud–radiation interactions in the southeast Atlantic basin

, 2021
. Southern Africa produces almost a third of the Earth’s biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood.

Dual-wavelength light-scattering technique for selective detection of volcanic ash particles in the presence of water droplets [PDF]

Atmospheric Measurement Techniques, 2015
A new method is presented in this paper which analyses the scattered light of individual aerosol particles simultaneously at two different wavelengths in order to retrieve information on the particle type.

Persistence of Severe Acute Respiratory Syndrome Coronavirus 2 in Aerosol Suspensions

Emerging Infectious Diseases, 2020
We aerosolized severe acute respiratory syndrome coronavirus 2 and determined that its dynamic aerosol efficiency surpassed those of severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome. Although we performed experiment only

Atmospheric aerosol attenuation effect on FD data analysis at the Pierre Auger Observatory [PDF]

, 2019
The atmospheric aerosol monitoring system of the Pierre Auger Observatory has been operating smoothly since 2004. Two laser facilities (Central Laser Facility, CLF and eXtreme Laser Facility, XLF) fire sets of 50 shots four times per hour during FD ...

The formation, properties and impact of secondary organic aerosol: current and emerging issues

, 2009
Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes ...

Use of electrochemical sensors for measurement of air pollution: correcting interference response and validating measurements [PDF]

Atmospheric Measurement Techniques, 2017
The environments in which we live, work, and play are subject to enormous variability in air pollutant concentrations. To adequately characterize air quality (AQ), measurements must be fast (real time), scalable, and reliable (with known accuracy ...
