The State of the Air 2010 shows that the air quality in many places has improved, but that over 175 million people

Aerosols: Integrating an understanding of source-receptor relationships with climate forcing on regional scales a paper presented by Chandra Venkataraman at National climate research conference, IIT Delhi, March 5-6, 2010.

In order to assess the role of meteorology as a diffusing or non-diffusing agent, this paper presents a 20 year analysis of the effects of meteorology on air pollution and has considered Delhi for pilot analysis. The study will be extended to 10 more cities in 2010.

Motor vehicles are a significant source of urban air pollution and are increasingly important contributors of anthropogenic carbon dioxide and other greenhouse gases.

The impact of air pollution on the human health and the ecosystem is increasingly been linked to the growing transport sector. A major intervention that Delhi is counting on is the extension of the metro rail system, to shift the motorized transport trends to the metro rail. The expected level of shift is uncertain, which depends on a number of factors.
