METHOD OF DYNAMIC MEASUREMENTS AND OPTIMAL ASSESSMENT OF THE PENETRATION DEGREE OF MARINE SALT AEROSOL INTO COASTAL PRODUCTION ZONES

Abstract

An accurate assessment of the emission of pollutants coming from the water surface is extremely relevant in studies of mass transfer between the sea and the atmosphere. The object of the study is a corrosive marine salt aerosol formed under the influence of wind, as a result of the dissipation of wave energy when hitting the shore. The subject of the study is the extent of the spread of sea salt aerosol under the influence of wind in coastal residential and industrial zones. The purpose of the study is to determine the nature of the change in wind speed over time, at which the total measuring signal at the output of the mobile meter would reach an extreme, i.e. the most reliable measurement result would be achieved. The aim of the study, when comparing the increasing and decreasing wind speeds, to determine such a dependence of wind speed on the current measurement time at which the measurement result would reach an extremum. The general task of estimating the amount of corrosive sea aerosol deposited in the coastal zone in this case is to estimate the amount of the current unsettled aerosol in the air. The proposed research method is to determine the penetration degree of sea salt aerosol into residential and industrial quarters, a dynamic measurement method is proposed, carried out using a mobile laboratory equipped with appropriate measuring equipment. The meter at point xi measures the aerosol generated by the wind at moment ti . For the optimal solution of the problem, the double averaging method is used. As a result a mobile measurement method is proposed to determine the degree of penetration of marine salt aerosol into the coastal production zone. The problem of determining the nature of the temporary change in wind speed in the coastal zone is solved with a known dependence of the amount of settled sea aerosol on the distance between the measuring point and the sea under the condition of a constant speed of movement of the mobile meter
