In a number of cities in India, air pollution is a growing problem, not only limited to the megacities, but also spreading through the tier II and tier III cities. Given a diverse mix of sources in these cities, with megacities dominated with transport sector and the secondary

Delhi is gearing up to host Commonwealth Games in October 2010. This latest analysis of air quality trends in Delhi and their implications on CWG 2010 by Dr. Sarath Guttikunda suggests innovative interventions for fast & effective air quality management.

The air quality index (AQI) is an "index" determined by calculating the degree of pollution in the city (as an average) or at the monitoring point and includes five main pollutants

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.

Singapore is the first city in the world to implement electronic road pricing (ERP) in September 1998. The ERP or congestion pricing system was successful for one important reason - the city operates a widely accessible public transport system (road and rail) which can support the shift to car-free transport.

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.

Like many cities in India (and in the developing world), Delhi lacks the necessary number of operational air quality monitors. This paper presents a proposal to monitor particulate pollution cheaply and effectively and a methodology to map the pollution over city for understanding the hot spots and studying exposure levels.

This document describes the methodology used in a recent project to measure pollutant emission factors and conduct detailed characterization of particulate matter (PM) emitted by

The air pollution is a growing problem in a number of cities around the world. Over the years, starting from the days of the infamous London smog and Los Angeles smog episodes, the cities around the world have established programs to better understand the air pollution sources and facilitated ways to control the pollution.

Policymakers in rapidly growing urban areas increasingly recognize that addressing air quality issues is an urgent priority. The developing countries should aspire to imitate the air pollution modeling systems, irrespective of the modeling limitations.
