Numerical implementation for the fluid location of atmosphere method

Numerical algorithms for the implementation of the fluid location of atmosphere (FLA) method are considered. The FLA method is designed to retrieve the mean effective fields of the atmospheric pollutant concentrations based on the measurement results. Different approaches to iterative solution of the mass conservation equation within the framework of this method are discussed. Stable convergent numerical scheme is proposed, which allows to significantly reduce calculation time. As an example the results of demonstration task to estimate the mean effective fine aerosol concentration field based on the photometric measurements at Ussuriysk monitoring site are presented.
