Simultaneous long-term measurements of near-surface air pollutants at an urban station, New Delhi, were studied during 2005–2012 to understand their distribution on different temporal scales. The annual mean mass concentrations of nitrogen dioxide ($$\hbox {NO}_{2})$$ NO2) , sulphur dioxide ($$\hbox {SO}_{2})$$ SO2) , particulate matter less than $$10\,\upmu \hbox {m}$$ 10μm ($$\hbox {PM}_{10})$$...
Semi-continuous measurements of organic carbon (OC) and elemental carbon (EC) and continuous measurements of black carbon (BC) and PM2.5 aerosols were conducted simultaneously during the winter period of 2010–2011 at Delhi, one of the polluted urban megacities in western part of the Indo-Gangetic Basin region. The average mass concentrations of OC, EC, BC and PM2.5 were about 54 ± 39, 10 ± 5, 12 ± 5...
