Abstract. Atmospheric pollution over South Asia attracts special attention due to its effects on regional climate, water cycle and human health. These are potentially growing owing rising trends of anthropogenic aerosol emissions. In this study, the spatio-temporal distributions from seven global models evaluated against retrievals NASA satellite sensors ground-based measurements for period 2000–2007. Overall, substantial underestimations loading found systematically in most model...

Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over European North American continents, this study aims at (i) apportioning error to responsible processes using timescale analysis, (ii) helping detect causes model error, (iii) identifying temporal scales most urgently requiring dedicated investigations. The analysis is conducted within framework third phase Air Quality Model Evaluation International...

Several communications claimed the first weeks of March that mitigation pollution observed at time was actually related these without considering seasonal variations emissions and meteorology also influence To determine specific impact quality northern Italy, we compared observations European...
Abstract This paper reviews the transformation processes that polycyclic aromatic hydrocarbons (PAHs) undergo in atmosphere. These can take place both gas phase and particulate/aerosol one. Among gas‐phase processes, most important ones are daytime reaction with • OH nighttime NO 3 . The relative importance of two depends on particular PAH molecule. For instance, gaseous naphthalene is mainly removed from atmosphere upon OH, while phenanthrene by Oxy‐, hydroxy‐, nitro‐PAHs main...

Abstract. As the third most important greenhouse gas (GHG) after carbon dioxide (CO2) and methane (CH4), tropospheric ozone (O3) is also an air pollutant causing damage to human health ecosystems. This study brings together recent research on observations modeling of O3 in Arctic, a rapidly warming sensitive environment. At different locations observed surface seasonal cycles are quite different. Coastal Arctic locations, for example, have minimum springtime due depletion events resulting...
