Effects of meteorological conditions on concentration of air pollutants in Delhi
Air pollution in Delhi is a serious environmental problem. In this paper, the effects of meteorological conditions on local air quality are quantitatively assessed by determining the relationships between concentrations of Suspended Particulate Matter (SPM), Respirable Suspended Particulate Matter (RSPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2) with meteorological parameters on monthly basis, from 2000 to 2006. The multi-linear regression approach, used in the study, has facilitated analysis of the air quality-meteorology relationship and predicted the concentrations of SPM and RSPM within a scatter of ±18% and of SO2 and NO2 within a scatter of ±14%.
