“The Supreme Court Friday approved the use of a common pollution code for Delhi-NCR to categorise the severity of the pollutants present in the air. The levels of pollution will be classified into four categories — moderate to poor, very poor, severe, very Severe or emergency. Accepting recommendations made by the Delhi and Central government, the apex court directed the Centre to notify the levels of four categories of pollution.  Beijing also has a similar pollution code where regular colour-coded alerts are issued based on the pollution levels. The court order comes nearly a month after the capital saw pollution levels rise to alarming levels, with thick smog enveloping the city. It lead to the Arvind Kejriwal government announcing a slew of temporary measures to bring pollution levels down to normal.

Shutting down of the Badarpur power plant, halting construction activity, vacuuming cleaning and sprinkling of water on roads, and banning the practice of burning dry leaves or waste were among the measures announced. Recently the top court has also banned the sale of fireworks in the capital in an effort to curb rising pollution levels.” The Indian Express. Read it on

Delhi government directs implementation of six measures to curb air pollution: The Indian Express

“Holding a high-level meeting, Screen Shot 2016-11-30 at 9.36.59 PM.pngDelhi Deputy Chief Minister Manish Sisodia on Wednesday directed immediate implementation of six new measures to curb the menace of air pollution in the national capital. The ideas and their proposals stem from scientific reports of Government of India by CPCB, CSIR and NEERI and orders of the National Green Tribunal (NGT). The National Environmental Engineering Research Institute (NEERI), a research institute, created and funded by Government of India, has been given the mandate to design and implement these solutions.

In collaboration with the PWD, NEERI will design and execute induced-draft creation units at five major traffic intersections in Delhi. The IDC at IIT Bombay will help NEERI design for these traffic intersections. Such a unit has the potential to reduce carbon monoxide and particulate emission by 40percent to 60percent emission in 20-30 metres of radius during peak hours of traffic. Pilot study executed in IIT Bombay on JVLR Road shows reduction of 55-76per cent for PM2.5 and 73-88 percent for PM10. Air quality sensors, anemometers, camera and counters will be mounted on these units for better mapping which will enable robust data assimilation and analysis.

This step will also execute directions of the Central Pollution Control Board (CPCB) to DPCC dated December 29 2015, which requires action on creating green buffers along traffic corridors, and reduce curbside pollution and intervene at road traffic intersections using different technologies, as per the directions. The Deputy CM also ordered that DPCC conduct the five following studies regarding air pollution along with NEERI, which will result in concrete deliverables, helping the Delhi Government to curb the menace of air pollution.

High-level meeting attended Environment Minister Imran Hussain and officials from PWD, Environment and Delhi Pollution Control Committee. CSIR NEERI, a science R and D institute of the Government of India, will design and implement the measures.

Five design and technical studies for targeted solutions to be conducted CSIR NEERI in collaboration with DPCC. Delhi is expected to witness dense to shallow fog over the next several days. Several flights were also delayed at the Delhi airport on Wednesday morning due to dense fog. As per the forecast, dense fog is expected across the city on Thursday as well, while both Friday and Saturday will see moderate fog. On Sunday, while the fog is expected to be shallow, the minimum temperature is expected to reach 9 degrees Celsius. Unfortunately, fog is expected to worsen the air quality of the city which has already touched “severe” levels at many places.” The Indian Express. Read it on

Hourly pollution data from 33 nations at your fingertips: The Times of India


Screen Shot 2016-11-26 at 12.41.24 PM.png“Delhi’s fight against air pollution vis-a-vis Beijing has been well documented. Now, data is available to show hourly air pollution levels in these cities. For example, PM2.5 levels around Beijing’s US embassy were way lower than Delhi’s RK Puram through most of Thursday.

“In fact, Beijing’s US embassy recorded far lower PM2.5 than Punjabi Bagh since November 19. But the US embassy area in Mongolia’s Ulaanbaatar often recorded hourly levels that were higher than Delhi. Data from more than 4,000 monitoring stations in 33 countries is now available openly to be used by researchers. A community of air quality scientists, software developers and data researchers who founded Open AQ — an open air data platform—are scraping air quality data from various government and research bodies to present it in a uniform format.

“US-based Open AQ, which is currently holding a two-day workshop Delhi, has a number of open data enthusiasts, including students, sensor developers, public policy experts and scientists among participants.

“They include experts from the Public Health Foundation of India, public transport expert from the World Resources Institute, app developers, air quality monitor manufacturers and entrepreneurs. Air quality data is usually available in different formats across the world. Several countries have their own air quality index system, making comparisons difficult. Christa Hasenkopf, an atmospheric scientist and co-founder of Open AQ, said the platform was built to address these inequalities in reporting of data.” The Times of India
