Proton‐transfer‐reaction mass spectrometry (PTR‐MS) allows real‐time measurements of
volatile organic compounds (VOCs) in air with a high sensitivity and a fast time response …

This paper presents a comprehensive assessment of historical (1990–2010) global
anthropogenic particulate matter (PM) emissions including the consistent and harmonized …

Accurate quantification of exposures to traffic-related air pollution in near-highway
neighborhoods is challenging due to the high degree of spatial and temporal variation of …

Soot particles, which are aggregated carbonaceous spherules with graphitic structures, are
major aerosol constituents that result from burning of fossil fuel, biofuel, and biomass. Their …

An inter-comparison study of instruments designed to measure the microphysical and optical
properties of soot particles was completed. The following mass-based instruments were …

Exploratory field measurements in the Mexico City Metropolitan Area (MCMA) in February
2002 set the stage for a major air quality field measurement campaign in the spring of 2003 …

In this paper, we report the results and analysis of a recent field campaign in August 2007
investigating the impacts of emissions from transportation on air quality and community …

Continuous ambient measurements with aerosol time-of-flight mass spectrometry (ATOFMS)
were made in an industrial/residential section in the northern part of Mexico City as part of …
