OPTIMIZATION OF PHOTOMETRIC MEASUREMENTS OF LOW GASES OF ATMOSPHERE IN COASTAL ZONES TAKING INTO ACCOUNT THE WIND DEPENDENCE OF MARINE AEROSOL OPTICAL DEPTH
The aim of research- to determine conditions and possibilities for optimization of sun- photometric measurements of atmospheric low gases in coastal zones.The analysis of known experimental research data has shown that in condition of non- industrial type coastal zones the atmospheric aerosol is almost fully contain marine aerosol. In this case both fine and coarse disperse components of atmospheric marine aerosol is divided to components depending on wind speed or not. Four optimization tasks on measurements of atmospheric low gases on given complex ronte containing marine and continental components are formulated and solved. Open composing the optimization tasks two limitation conditions were used where the first one was imposed on integral of functional dependence of wind speed on route and the second one on integral of functional dependence of winds pressure on route. The main functional of optimization was considered in two variants: (a) as on integral of Bougner-Ber formula on route, and (b) as a linear polynomial, formed in the case if the exponent in Bougner-Ber formula is too low than one. Solution of composed tasks on non-conditional variation optimization make it possible to derive in two cases fully analytical formulas of optimum dependence of wind speed on length of passed route.In rest two cases the optimum solution was absent or the derived transcendent equation not allowed to form the analytical formula.
