The Air Quality Release app by China National Environmental Monitoring Center is a lifestyle app available for iPhone users. It is a free app that provides real-time air quality information for 338 cities in China, including provincial capitals and other major cities. It also offers air quality forecasts and warnings for provinces, autonomous regions, and municipalities.

With this app, users can stay informed about the air quality situation in their city and receive guidance for travel and health. The app provides the most up-to-date data, ensuring that users have access to the latest information.

One of the notable features of the app is its detailed city forecasts. It offers timely forecasts of air quality levels, including the range of air quality index and the primary pollutants for the next five days. Users can also receive alerts from local governments.

Additionally, the app provides comprehensive air quality situation forecasts. It supports the display of trends in various types of pollutants, allows for air quality comparisons between multiple cities, and provides a nationwide and provincial overview of air quality conditions.

The air quality forecasts are based on data collected from participating cities, environmental monitoring units, regional forecast centers, and other relevant environmental protection forecast departments. The forecasts are derived from monitoring of pollution sources, implementation of new air quality standards, analysis of atmospheric pollution processes, and consultations among monitoring units.

Please note that the air quality forecast data provided in this app is for public reference only and should not be used for local air quality management and activation of warnings.
