Study of Distribution Ice-Forming reagent in the Boundary layer of the atmosphere When Exposed by Ground Aerosol Generators NAG-07M

Abstract

The paper describes the technical means, methods, and results of experimental studies of the spread of ice-forming agents in the boundary layer of the atmosphere under the action of ground-based aerosol generator NAG-07M. Comparison of the data on sampling by an AVA 3-240-01S probe mounted aboard Vilga-35A aircraft with aerosol propagation calculations using a 3-D SeedDisp model shows 1. The concentration of silver iodide measured in the atmosphere was above background one to a height of 1200 m at distances of 3 to 9 km from the place of the generator installation. 2. The developed SeedDisp numerical model in general qualitatively correctly describes the distribution of silver iodide aerosols in the boundary layer and the free atmosphere under the action of ground-based aerosol generator NAG-07M. Thus, the coefficient of correlation of the measured and calculated by model values of the silver iodide particles concentration in the sub-cloud layer exceeded the value of 0.7.
