Nitrogen dioxide (NO2), a combustion-generated oxidant gas, is widely present in indoor and outdoor environments. Outdoors, where it comes primarily from combustion engines, industry, and power generation, it is a precursor to particles and ozone. Indoors, NO2 is generated by gas cooking and heating, and it exists as a gas along with other oxides of nitrogen. Many epidemiological studies have e...

[1] Nitrogen dioxide (NO2) is a key species in studying photochemical smog and formation mechanisms of nitrate in fine particles. However, the conventional commercially available chemiluminescence (CL)-based method often has uncertainties in measuring NO2 because of interferences with other reactive nitrogen species. In this study, an Aerodyne Cavity Attenuated Phase Shift Spectroscopy (CAPS) N...

It has been well documented that air pollution adversely affects health, and epidemiological pollution-health studies utilise pollution data from automatic monitors. However, these automatic monitors are small in number and hence spatially sparse, which does not allow an accurate representation of the spatial variation in pollution concentrations required for these epidemiological health studie...

Ground-based measurements of ozone and NO2 differential slant columns by the SAOZ (Système d’Analyse par Observations Zénithales) and UT-GBS (University of Toronto Ground-Based Spectrometer) instruments during the MANTRA 2004 field campaign are presented herein. During the afternoon of 28 August, a thunderstorm passed over the instruments, which were installed at Vanscoy, Saskatchewan (52 N, 10...
