Atmospheric air monitoring is a systematic, long-term assessment of the level of certain types of pollutants by measuring their amount in the open air. Atmospheric air monitoring is an integral part of an effective air quality management system and is carried out through environmental monitoring networks, which should support timely provision of public information about air pollution, support compliance with ambient air quality standards and development of emission strategies, support for air pollution research.The work is devoted to existing air monitoring technologies: ground (sensors, diffusion tubes, etc.) and remote resources (satellites, aircraft, etc.). In addition, standards of air quality assessment (European and American) are described. As an example, we consider the European Air Quality Index (EAQI) and the Air Quality Index according to EPF standards: indicators by which these indices are calculated, the ranking of air status depending on the value of the index are described.AQI (Air Quality Index) is used as an indicator of the impact of air on the human condition. The European Air Quality Index allows users to better understand air quality where they live, work or travel. By displaying information for Europe, users can gain an understanding of air quality in individual countries, regions and cities. The index is based on the values of the concentration of the five main pollutants, including particles less than 10μm (PM10), particles less than 2.5μm (PM2.5), ozone (O3); nitrogen dioxide (NO2); sulfur dioxide (SO2). To conclude, ground stations give a more accurate picture of the state of the air at a point, while satellite image data with a certain error (due to cloud cover, etc.) can cover a larger area and solve the problem of coverage of stations in the area. There is no single standard for calculation. Today, the European Air Quality Index (EAQI) is used in Ukraine and Europe.

Дніпропетровський національний університет імені Олеся Гончара ВІДНОВЛЕННЯ ФОРМИ РОЗПОДІЛУ ТОЧОК РОЗЛАДНАНЬ НА ЧАСОВОМУ РЯДІ ВАЛЮТНИХ КОТИРУВАНЬ Розглянуто форму розподілу, утвореного точками зміни статистичних характеристик ряду курсів валют. Проаналізовано можливості його відновлення з використанням параметричного та непараметричного підходів.Ключові слова: статистика, визначення розладнань, біржова торгівля, котирування, часовий ряд, нестаціонарні процеси, відновлення розподілів.Рассмотрена форма распределения, образованного точками изменения вероятностных характеристик временного ряда валютных котировок. Проанализированы возможности его восстановления с использованием параметрического и непараметрического подходов.Ключевые слова: статистика, определение разладок, биржевая торговля, котировки, временной ряд, нестационарные процессы, восстановление распределений.The distribution formed by change-points of financial quotes time series has been reviewed. Possibilities of its estimation using parametric and nonparametric approach have been analyzed.
