Since India has different climatology, statistical analysis of trace gases over distinct regions is very important to take necessary actions to control the pollutants. A network of stations has been initiated by Indian Space Research Organization in India to retrieve data on atmospheric trace gases. However, only few studies have been done on statistical analysis of trace gases on distinct regions of India. In this paper discussed statistical behavior of surface ozone (O3 ) and black carbon (BC) mass concentration in different regions of lndia like rural, semi-urban, urban, and hill stations. The diurnal variation of rate of change of O3 is used to analyze trace gases chemical environments of various locations. Results showed that surface ozone at Anantapur is similar to Kannur, and lower than that at Dayalbagh, an urban site; Darjeeling and Port Blair, a high altitude and hill site. In India, some locations reported lower surface ozone mixing ratios than Anantapur like Dibrugarh, a semi-urban location; Kullu, Pantnagar, semi-urban; Hyderabad, an urban site; Trivendrum, a coastal site; Chennai, an urban site; and Joharapur, a rural site. High concentrations of black carbon were observed at Kanpur, an urban site (6-20 µg/m3 ) followed by Hyderabd, an urban site (1.5-11.2 µg/m3 ), and Ahmedabad (0.2-10.2 µg/m3 ). Results showed that Mohal-Kullu, and Darjeeling reported high BC compared with other hill stations like Ooty and Nainital, and semi-arid rural stations also reported substantial BC
