Abstract: Ground-based observations of electric field, Aitken nuclei (AN) and concentrations of trace gases in fair weather conditions are made at four locations having different environmental status (oceanic, hill-top, semi-urban and industrial). The influence of concentration of Aitken nuclei and trace gases on atmospheric electric field at these locations is examined and an attempt is made to obtain the effective attachment coefficients and mean life time of small ions at the locations. The results show that, in clean and relatively less polluted regions, the diurnal as well as monthly variation of fair weather electric field is significantly (0.1 and 0.0 1%) correlated with Aitken nuclei concentration. An examination of gaseous concentrations suggests that the electric field gets adversely affected in the regions which are enriched with SO2 loading and particulate matter from the industries. The values of attachment coefficient and mean lifetime of small ions obtained in the present set of study reveal that the environmental status is an important factor to affect the air pollutants which, in turn, affect the electric field.
