Abstract: The point discharge currents (PDCs) have been measured at 3 locations, viz. (i) on the seashore., (ii) at the observatory 1.5 km west of the coast line, and (iii) at a distance of 5 km further west to the point of observation in (ii) and adjacent to a locoshed. Measurements at locations (i) and (iii) have been carried out under fair weather conditions with an artificial point raised at a height of 4 km above the ground. At location (ii) they have been recorded at heights 4 and 8 km under both fair and bad weather conditions. It is found that the PDC becomes positive from negative and the potential gradient increases as one move from the coast to the interior. The airborne pollutants seem to contribute to the increase of the positive currents while eat the sea coast the bubble breaking due to wave action is responsible for the negative currents.
