Objects: atmospheric environment, water environment. The goal of the project is to create new methods of modeling the dynamics of pollution in the atmospheric and marine environment, based on modern knowledge of environmental hydrodynamics, parameterizations of physical and chemical transformations of pollution, inverse modeling methods for establishing unknown input data of models, researching developed means of direct and inverse modeling of radioactivity dynamics during radiation incidents and implementation of the developed methods into the information web system of analysis by means of inverse modeling of unknown sources of radioactive pollution in Ukraine and abroad. The report presents the results of calculations of the Lagrangian model of atmospheric transport in the inverse mode and developed algorithms for solving the inverse problem of atmospheric transport, based on which the possible sources of ruthenium-106 entering the atmosphere in September-October 2017 were investigated. in the atmosphere and marine environment based on the solution of conjugate equations. The developed algorithms of inverse modeling of atmospheric transfer are integrated into a new information web system for the analysis of unknown sources of radioactive pollution in the air, which allows automation of the solution of the inverse problem when detecting radioactive pollution by radiological measurement networks in any region of the world. KEY WORDS: inverse calculations, information web system, unknown sources of pollution, ruthenium-106, Black Sea, fires in the Chornobyl exclusion zone.  Product Description popup.authors Bejenar Julia Romanivna Brovchenko Igor Oleksandrovich Kovalets Igor Vasylovych Kovalets Katerina Ivaniva Kovalets Sergey Ivanovych Sinkevich Roman Oleksandrovich Khurtsilava Konstantin Viktorovich Shrubkovsky Oleksandr Viktorovich popup.nrat_date 2023-12-15 Close
