TL;DR: In this article, an analysis of high resolution OA spectra was performed at the T0 urban supersite in Mexico City with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) and complementary instrumentation.

TL;DR: In this paper, the MI-LAGRO field campaign in Mexico City used a high resolution AMS spectra to identify a biomass burning organic aerosol component, which includes several large plumes that appear to be from forest fires within the region.

TL;DR: The results of the MILAGRO campaign as discussed by the authors showed that PM 2.5 and PM 1 concentrations showed a marked impact of road traffic emissions (at rush hours), with levels of coarse PM remaining elevated during daytime.

TL;DR: A wide array of volatile organic compound (VOC) measurements was conducted in the Valley of Mexico during the MCMA-2002 and 2003 field campaigns as discussed by the authors, where four distinct analytical techniques were used: whole air canister samples with Gas Chromatography/Flame Ionization Detection (GC-FID), on-line chemical ionization using a Proton Transfer Reaction Mass Spectrometer (PTR-MS), continuous real-time detection of olefins using a Fast Olefin Sensor (FOS), and long path measurements using UV Differential Optical Absorption Spect

TL;DR: The average 24-hr PM10 concentrations over the period of study at the core sites in Mexico City were 75 H g/m3 as mentioned in this paper, which was the highest 24-hour PM10 concentration for seven samples taken during the study period.
