Air is an iPhone application developed by RocKontrol Technology Group Co. Ltd., available for free in the Lifestyle category. This app responds to the development concept proposed by the party in the Fifth Plenary Session of the 18th Central Committee: innovation, coordination, green, openness, and sharing.

Air uses a model of "grid-type layout + multi-dimensional data integration + spatiotemporal data analysis" to generate comprehensive information about six pollutants in time and space dimensions. It provides real-time dynamic monitoring of data through encrypted grid layout. The backend data analysis system, based on GIS, screens, calibrates, statistically analyzes monitoring data, and generates dynamic graphics. This enables nationwide analysis of the spatiotemporal dynamic changes of atmospheric pollutants, source identification, tracking pollutant diffusion trends, and maximizing regulatory control over pollution sources, providing direct evidence for environmental law enforcement and decision-making.
