The data correspond to the conditions of June 2000 at latitude 50 N in the altitude range of 15–55 km. Calculations were performed using the interactive two-dimensional SOCRATES model. Forecasts of atmospheric greenhouse gas content of the Intergovernmental Panel on Climate Change RCP 4.5 for the year 2000 were used as initial data for calculations. Calculations of the chain length of zero cycles were carried out using the algorithm proposed earlier by the author for determining the speed of the limiting stage of the catalytic cycle.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены численные данные о длине цепи так называемого нулевого кислородного цикла, т.е. такого цикла, в котором не происходит разрушения озона, как в каталитических циклах. Данные соответствуют условиям июня 2000-го года на широте 50° с.ш. в диапазоне высот 15–55 км. Расчеты проводились с помощью интерактивной двумерной модели SOCRATES. В качестве начальных данных для расчетов использовались прогнозы атмосферного содержания парниковых газов Межправительственной группы экспертов по изменению климата RCP 4.5 для 2000-го года. Расчеты длины цепи нулевых циклов проводились с помощью предложенного ранее автором алгоритма определения скорости лимитирующей стадии каталитического цикла.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chemical families</kwd><kwd>catalytic cycles</kwd><kwd>chain process</kwd><kwd>limiting stage of the chain process</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>химические семейства</kwd><kwd>каталитические циклы</kwd><kwd>цепной процесс</kwd><kwd>лимитирующая стадия цепного процесса</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Zelenov V.V., Aparina E.V. // Russ.
