The ozone layer will recover by 2035. If the correct calculations of scientists, by this time the ozone concentration rises to the level of 1980. The article, in which a group of scientists from different countries, from Britain to Japan, analyzes the recovery of the ozone layer, is aimed for publication in the journal Atmospheric Chemistry and Physics. Researchers, using data on atmospheric dynamics, the mathematical model is designed to answer the question of how to change over time the concentration of ozone.
