Abstract
An overview of methods for calculating air quality indices (AQIs) widely used abroad to provide the population with information on air quality is presented. Foreign AQIs are used in available mobile applications, in interactive global display of air quality, including the territory of the Russian Federation. In Russia, AQI has not yet been used to inform the population. Taking into account the principles of grading the classes of foreign indices, a scheme for calculating the Russian variant of the index AQI-R using Russian air quality standards is proposed. The comparison of AQI based on the European Union scheme (AQI-EU) and AQI-R calculated from observations in Moscow showed that according to the EU scheme, the air quality assessment is stricter and more often indicates poor air quality. The differences in the estimates are associated with excessive requirements for the concentration of PM10 and PM2.5 in the AQI-EU. For the development and adoption of the national AQI, it is necessary to take into account Russian priorities in assessing air quality and regional features of air pollution.
