Factors associated with NO2 and NOX concentration gradients near a highway
Atmospheric Environment, 174, 214–226.
author keywords: Near-road; NO2; Oxides of nitrogen; Nitrogen dioxide; Dispersion
TL;DR:
Variability in near-road concentrations is influenced by local meteorology and ambient O3 concentration, and wind direction parallel to the highway was related to an increased magnitude of both dCNO2 /dx and dC NOX /dx, likely shrinking the zone of elevated concentrations occurring near roads.

Air Quality, Atmosphere & Health, 10(5), 611–625.
author keywords: Near road; NO2; Oxides of nitrogen; Nitrogen dioxide; Dispersion
TL;DR:
A new regression modeling approach to estimate on-road nitrogen dioxide (NO2) and oxides of nitrogen (NOX) concentrations and near-road spatial gradients using data from a near- road monitoring network showed that the diurnal cycle of the background NO2/NOX ratios were a driving factor in the on- road and downwind NO2-NOx ratios.

TL;DR:
Indoor ultrafine PM levels were roughly 3-10 times lower than outdoor levels, depending on the monitor location, and CO, NO(2), and SO(2) levels were shown to be similar to values that produced increased risk of chronic obstructive pulmonary disease hospitalizations in the Vancouver studies.

The effect of a tall tower on flow and dispersion through a model urban neighborhood: Part 1. Flow characteristics
Journal of Environmental Monitoring, 11(12), 2163–2170.
Contributors: D. Heist *, L. Brixey*, * , G. Bowker*, S. Perry* & R. Wiener*
MeSH headings : Air Pollutants / analysis; Environmental Monitoring / methods; Kinetics; Models, Theoretical; New York City; Wind
TL;DR:
Results reveal that a tall tower has a dramatic effect on the flow in the street canyons in the neighboring blocks, enhancing the exchange between the street canyon flow and the freestream flow aloft.

The effect of a tall tower on flow and dispersion through a model urban neighborhood: Part 2. Pollutant dispersion
Journal of Environmental Monitoring, 11(12), 2171–2179.
Contributors: L. Brixey*, D. Heist *, * , G. Bowker*, S. Perry* & R. Wiener*
MeSH headings : Air Pollutants / analysis; Environmental Monitoring / methods; Kinetics; Models, Theoretical; New York City; Time Factors; Wind
TL;DR:
This article is the second in a two-paper series presenting results from wind tunnel and computational fluid dynamics (CFD) simulations of flow and dispersion in an idealized model urban neighborhood that was characterized by regular city blocks of three-story row houses with a single 12-story tower located at the downwind edge of one of these blocks.

Time-series analysis to study the impact of an intersection on dispersion along a street canyon
Journal of Environmental Monitoring, 11(12), 2153–2162.
Contributors: * , A. Eisner*, I. Hahn*, C. Fortune*, Z. Drake-Richman*, L. Brixey*, M. Talih *, R. Wiener*, W. Ellenson*
MeSH headings : Air Pollutants / analysis; Air Pollution, Indoor / analysis; Atmosphere / chemistry; Environmental Monitoring / methods; Kinetics; New York City; Particulate Matter / analysis; Time Factors; Vehicle Emissions / analysis; Wind
TL;DR:
Low but significant values of the cross-correlation function (CCF) underscore the turbulent nature of plume transport along the street canyon and suggest that flow switching around corners or traffic-induced turbulence at the intersection may have aided dilution of the PM plume from the highway.

Transport of exhaled particulate matter in airborne infection isolation rooms
Building and Environment, 44(1), 44–55.
author keywords: Airborne infection isolation room; Aerosol transport; Computational fluid dynamics; Indoor air quality; Particle transport
TL;DR:
Investigation of the characteristics of the spatial velocity and concentration profiles which might result in health care workers’ exposure to a pathogenic agent in an airborne infection isolation room (AIIR) suggest that unintended exposures are possible despite the ventilation system.

Transport of airborne particles within a room

author keywords: indoor air; aerosol; turbulent diffusion; dispersion; nondimensional modeling; furnishings

TL;DR:
A technique used to analyze contaminant transport in the wake of a bluff body under controlled experimental conditions for application to aerosol transport in a complex furnished room suggests that turbulent diffusion is a significant factor in contaminant residence time in a furnished room.
