Abstract
Meteorological parameters (temperature, humidity, wind speed and wind direction) can be linked to air pollutants concentration levels in any area. The present study purposed to establish the relationship between meteorological parameters and selected criteria air pollutants concentration levels in Delhi. To infer spatial and temporal pattern of air pollutants and relationship with meteorological parameters, the secondary data for criteria pollutants as well as meteorological data (temperature, humidity, wind speed and wind direction) of selected sites were procured from a governmental agency “System of Air quality and weather Forecasting And Research (SAFAR)” for the period of four years (2013 to 2016). Microsoft excel was used for graphical representation purpose. Pearson correlation to establish pollutants relation with meteorological parameters was done by using SPSS. The study found that 2013 was the most polluted year and 2016 was the least in Delhi. It also showed that site 1 which is located in south Delhi is most polluted with regards of gaseous pollutants however; site 6 which is located in north Delhi is the most polluted site in terms of particulate matter. Some meteorological parameters have great influence on the spatial and temporal pattern of criteria pollutants in the selected sites. PM has negative correlation with temperature and humidity while in most sites NOX (NO & NO2) have positive relation with temperature. O3 also have positive relation with temperature because temperature accelerates formation of ozone. However, O3 has negative relationship with relative humidity because precipitation washes out the pollutant concentration. Generally, wind speed has no effect on concentration of air pollutants.
