Abstract. The near-surface atmospheric electric field and microparticles concentrations variations relationship was studied. The data obtained from Geophysical Observatory «Mikhnevo» and Geophysical Monitoring Center by IGD RAS were analyzed under the fairy weather conditions. The ratio of half an hour mean potential gradient values inside the megacity to the values outside of its influence region were calculated with the ratio monthly mean magnitude less than 1. The theoretical-numerical model developed was used to show the inversely proportional bond between the ratio and atmospheric aerosol pollution and to estimate the aerosol particles concentration based on the experimentally received ratio data. Measured electric field potential gradient values were compared to key air pollution indicators – NO_x, SO₂, CO and particulate matter (PM2.5, PM10).

Keywords: atmospheric electric field, technogenic aerosol, aerosol particles, metropolis, environmental pollution.
