Air pollution is a growing problem in most cities (big and small). The "Daily Dose" aims to disseminate the best available information on air pollution and engage in discussions to better understand the process of air quality management. For more details visit https://www.urbanemissions.info
Click on the Delhi map to read the current level of pollution and calculated health index. The health index is calculated by staff @ http://www.aqicn.org and not an official release of authorities responsible for monitoring in Delhi.
Data from two monitoring stations is analyzed in this paper - (1) a traffic junction @ ITO and (2) Delhi College of Engineering. At the monitoring sites, AQI is often more than the healthy levels of 150 (on a scale of 0 to 500). The ITO is a traffic junction and accounted for only 19% of the days less then 100 AQI and 33% of the days less than 150. The DCE in the north and tends to measure lower than the city averages and yet struggled to stay in the green with only 24% of the days less than 150 AQI.
In Figures below, the winter months are highlighted with a blue box for each year. The winter months experience the worst pollution in each year starting in October and leading up to the February, the following year. For more details, download the full report.
The “Clean Air for Delhi 2010 and Beyond” program is an advanced notification system for daily air quality in the National Capital Region of Delhi, developed through technical assistance supported by the French Government. The program, started during the 2010 Commonwealth Games, is implemented by two French firms, Aria Technologies and Léosphère, in collaboration with (and for) the Central Pollution Control Board, New Delhi, India. It is designed to provide pollution alerts to the public and the media with the aim of minimizing future instances of higher health impacts. See the Press Release in October, 2010.
This programme is implemented by Aria Technologies and Léosphère in collaboration with the Central Pollution Control Board.

Mr Jérôme Bonnafont, Ambassador of France to India, introduced this programme which was presented by Prof S. P. Gautam, Chairman of the Central Pollution Control Board (CPCB) and Dr Armand Albergel, Representative of Aria Technologies and Léosphère during a press meet on Friday, 22nd October,2010.
The “Clean Air for Delhi 2010 and Beyond” programme covers an area of 52km x52km of the NCR. While the system is based on a modelling exercise combining the atmospheric physics of weather forecasting and atmospheric chemistry, the inputs include emission intensities from multiple sources contributing to air pollution. The data includes information from the existing monitoring network operated by CPCB and a laser-based lidar network deployed in the region. The programme provided 48-hour forecast on air quality during the Commonwealth Games and it continues its day-to-day operations under the leadership of CPCB in Delhi. When the system is fully established for Delhi, its replication in other cities may be considered.

The Jawaharlal Nehru Stadium was fabulously well-lit in the days leading up to, and during, the Commonwealth Games. But the lights came at a cost, with the stadium having drawn up a power bill of over Rs 1 crore for a month. Here's a look at how much power major stadiums in the city consumed between September 15 and October 15, and how much it cost.
Today is the last day for this section, "CWG Watch - Air Pollution in Delhi" on this blog. In the future, there will be articles on the model performance during the CWG period and the future plans for extending this study to other cities. Please come back and check the reports and papers @ urbanemissions.info
The daily forecasts will continue to be posted here in the coming months. ****
The air quality forecasting system for the National Capital Region (NCR) of Delhi is now operational and issuing daily reports to inform on the movement of the criteria pollutants in the city. This blog is now dedicated to support delivery of this information for the next two weeks to support the Commonwealth Games activities in Delhi, 2010. Page is updated every morning with forecast information for that day and next day (48 hrs). Among many results available for the public to view, access to the animations of hourly concentrations for the individual pollutants for a period of 48 hours is here. These are not archived - latest is animated here.
For the Commonwealth Games venues, click on the dates to access the forecast information for today (October 15th) and tomorrow (October 16th).
The above maps indicate the Air Quality Index (AQI) at the CWG venues, as a forecast from the models. Details on the modeling architecture and the system are available here.
*********** Modeling team for this project is Aria Technologies SA and Leosphere SA (both from Paris, France). They have previously developed similar systems for the Beijing Olympic Games 2008 and the Turin Winter Olympic Games 2006, and have started working with the city of Rio de Janeiro, in preparation for the Olympic Games 2016.

Today is the last day of the CWG 2010 in Delhi, India. Since, this morning, the traffic has been very less in the city compared to the other days, due to closing down of a number of institutions, malls, schools, etc.

Based on the examples across the globe, a new methodology is developed to estimate the air quality index for Delhi, India. New paper in the SIM-series, No.35 - "Air Quality Index for Delhi, India: Trend Analysis & Implications for 2010 Commonwealth Games" presents the methodology adjusted to reflect the new ambient air quality standards issued in November, 2009 by the Central Pollution Control Board of India.
