Abstract
The present paper reports a study on the dependence of tropospheric ozone on some of its precursors, namely NOx, PM10, and SO2 during summer monsoon over a highly polluted Kolkata region megacity of India. The intrinsic multicollinearity has been explored through Bartlett’s sphericity test. Subsequently, principal component analysis has been implemented to identify the principal components with maximum factor loadings, and accordingly, the most influential ozone precursors have been extracted. Finally, after fitting some continuous and discrete distributions to the extracted precursors, the intrinsic uncertainty has been investigated by maximizing Shannon entropy. The normal distribution has been identified to generate the maximum entropy probability distribution for surface ozone and its precursors. Future directions have been stated at the end of the study.
