“…The four days duration back trajectories of the air flows [9], calculated by the HYSPLIT software package [10][11][12][13] for 500 m altitude above ground level, were used as information on the dynamics of the atmosphere. In this work the use of back trajectories on the single altitude means that the results of simulation discussed below represent the quasi-two-dimensional fields of the submicron aerosol concentration distribution in space, i.e.…”

The method of Fluid Location of the Atmosphere (FLA) [1][2][3] is the development of back trajectory statistics methods (BTS) [4][5][6], which allow to evaluate spatial structure of atmospheric contaminants, which are measured in a finite number of monitoring sites. In any variant of the BTS method, a fixed (Euler) grid is used to divide the investigated region into a set of fixed volume spatial cells. The common example of a fixed grid is a latitude -longitude grid. However, a latitude -longitude grid becomes inconvenient for solving some tasks, such as reconstructing of the concentration fields in the Polar Regions. The aim of this work is to build an alternative grid for the tasks of the FLA method, as well as to compare and analyze simulation results obtained on the basis of various grids.

“…The HYSPLIT software package [7][8][9][10] was used for calculation of back trajectories of air particles. The threedimensional back trajectories lasting 96 hours (four days) each, starting every hour at the location of the AERONET network monitoring point at 6 levels from 500 to 5500 m were calculated.…”

The results of the estimation of submicron atmospheric aerosol horizontal fluxes by the method of Fluid Location of the Atmosphere (FLA) are presented. For this purpose, the three-dimensional problem of reconstructing the spatial structure of the aerosol distribution taking into account wet and dry deposition of aerosol particles on the underlying surface is solved numerically. The initial data were the results of photometric measurements during 2016 on the Middle Urals.
