Abstract


Air Pollution is a precarious issue for the City Dwellers. It is important to control and mitigate the Air Pollution in exceedingly Polluted Area of the City. Due to limited number of monitoring stations by the environmental agency in the city spatial interpolation tool in GIS predicts the pollutants concentrations at unmonitored stations we can get vital information about the distribution pattern of the air pollutions. In this paper evaluation of the Air Quality Data for the important pollutants like PM10, PM2.5, Ozone, and NOx is represented in GIS for whole city of Pune. A Temporal Analysis is also been done for the months of February, March and April year 2015. The most spatial interpolation techniques from inverse distance weighing, kriging, splining and nearest neighbor. The most suitable method for GIS mapping is professed as Inverse Distance Weighing according to the monitoring stations spatial distribution data available was selected for the interpolation.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
