TL;DR: In this paper, the performance of the EPA Federal Reference method for monitoring the ambient concentrations of NO2 was evaluated using data from a recent field campaign in Mexico City, where data from standard chemiluminescence monitors equipped with molybdenum oxide converters were compared with those from Tunable Infrared Laser Differ- ential Absorption Spectroscopy (TILDAS) and differential optical absorption spectrograph (DOAS) instruments.

TL;DR: An Aerodyne Aerosol Mass Spectrometer (AMS) was deployed at the CENICA Supersite, during the Mexico City metropolitan area field study (MCMA-2003) from 31 March-4 May 2003 to investigate particle concentrations, sources, and processes as discussed by the authors.

TL;DR: In this article, the evolution of ozone (O3) and 13 volatile organic compounds (VOCs) in the boundary layer of Mexico City was investigated during 2000-2004 to improve our understanding of the complex interactions between those trace gases and meteorological variables, and their influence on the air quality of a polluted megacity.

TL;DR: In this article, real-time measurements of atmospheric mercury were made at a downtown urban site, and a rural site on the outskirts of Mexico City, during March 2006, and the episodic increases observed were attributed to plume impacts from industrial point source emissions.

TL;DR: In this paper, the performance of the EPA Federal Equivalent Method (FEM) technique for monitoring ambient concentra- tions of O3 via ultraviolet absorption (UV) has been evaluated using data from the Mexico City Metropolitan Area field campaign (MCMA-2003).
