Air Quality in Nagpur (Maharashtra, India)

While industries, power plants, mines and vehicles are blamed for increasing exposure to air pollution, there are many lesser-known sources which are significantly poisoning the quality of air. Virendra Sethi, professor at Centre for Environmental Science and Engineering, Indian Institute of Technology, Bombay, whose 40 research papers have been published in various international journals, talks about what really is adding to rural and urban air pollution.

It is a myth that pollution is completely dependent on population or number of vehicles in a city. There are various other factors that degrade a city's ambient quality of air. In case of Nagpur, it is surrounded by thermal power stations in Koradi, Khaparkheda, Butibori, Mauda and industries in Hingna and Butibori. Depending on the wind direction, pollutants from all these sources come in the city, this increasing it pollution levels. Read the full article @ Times of India

Below are some extracts for the city of Nagpur, from the air quality forecasting system for India.

Fire INventory from NCAR (FINN) - A Daily Open Fire Emissions Extracted for the Indian Subcontinent

Open biomass burning makes up an important part of the total global emissions of greenhouse gases, reactive trace gases, and particulate matter. Although episodic in nature and highly variable, open biomass burning emissions can contribute to local, regional, and global air quality problems and climate forcings. The Fire INventory from NCAR (FINN) model provides high resolution, global emission estimates from open burning; these emissions have been developed specifically to provide input needed for modeling atmospheric chemistry and air quality in a consistent framework at scales from local to global. The inventory framework produces daily emission estimates at a horizontal resolution of ~1 km2. The product differs from other inventories because it provides a unique combination of high temporal and spatial resolution, global coverage, and estimates for a large number of chemical species.

CNG in India

In its efforts to move towards a gas-based economy, the NDA government plans to increase natural gas contribution towards India’s energy mix to 15% from the current 6.5%. Read the full article @ VCC
