Linking Switzerland's PM₁₀ and PM_2.5 oxidative potential (OP) with emission sources by S. K. Grange, S. K. Grange, G. Uzu, S. Weber, J.-L. Jaffrezo, C. Hueglin

“…<p>Particulate matter (PM) is the air pollutant that causes the greatest deleterious health effects across the world, so PM is routinely monitored within air quality networks, usually in respect to PM mass or number in different size fractions. …”

Examining the implications of photochemical indicators for O₃–NO_<i>x</i>–VOC sensitivity and control strategies: a case study in the Yangtze River Delta (YRD)... by X. Li, M. Qin, L. Li, K. Gong, H. Shen, J. Li, J. Hu

“…<p>Ozone (O<span class="inline-formula">₃</span>) has become a significant air pollutant in China in recent years. O<span class="inline-formula">₃</span> abatement is challenging due to the nonlinear response of O<span class="inline-formula">₃</span> to precursors nitrogen oxides (NO<span class="inline-formula">_<i>x</i></span>) and volatile organic compounds (VOCs). …”

Measurement report: Atmospheric nitrate radical chemistry in the South China Sea influenced by the urban outflow of the Pearl River Delta by J. Wang, J. Wang, J. Wang, H. Wang, H. Wang, H. Wang, Y. J. Tham, Y. J. Tham, L. Ming, Z. Zheng, Z. Zheng, G. Fang, C. Sun, C. Sun, C. Sun, Z. Ling, Z. Ling, Z. Ling, J. Zhao, J. Zhao, J. Zhao, S. Fan, S. Fan, S. Fan

“…<p>The nitrate radical (NO<span class="inline-formula">₃</span>) is a critical nocturnal atmospheric oxidant in the troposphere, which widely affects the fate of air pollutants and regulates air quality. Many previous works have reported the chemistry of NO<span class="inline-formula">₃</span> in inland regions of China, while fewer studies target marine regions. …”

Eurodelta multi-model simulated and observed particulate matter trends in Europe in the period of 1990–2010 by S. Tsyro, W. Aas, A. Colette, C. Andersson, B. Bessagnet, B. Bessagnet, G. Ciarelli, F. Couvidat, K. Cuvelier, K. Cuvelier, A. Manders, K. Mar, M. Mircea, N. Otero, N. Otero, M.-T. Pay, V. Raffort, Y. Roustan, M. R. Theobald, M. G. Vivanco, H. Fagerli, P. Wind, P. Wind, G. Briganti, A. Cappelletti, M. D'Isidoro, M. Adani

“…An in-depth trend analysis has been performed for PM<span class="inline-formula">₁₀</span> and PM<span class="inline-formula">_2.5</span> for the period of 2000–2010, based on results from six chemical transport models and observational data from the EMEP (Cooperative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe) monitoring network. Given harmonization of set-up and main input data, the differences in model results should mainly result from differences in the process formulations within the models themselves, and the spread in the model-simulated trends could be regarded as an indicator for modelling uncertainty.…”
