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