The AIRTHINGS project will leverage the emerging technologies through Internet of Things intelligent air quality measuring sensors providing new, real time data through internet - forming network of connected cities jointly monitoring air quality, cloud based "Open data" system with predictive analytics and advanced machine-learning capabilities enabling public bodies’ timely actions. In combination with city specific guidelines and methodologies for air quality monitoring, establishment of common policy framework analysis towards decrease of regional pollutants and 3D MEMO, 3D MARS-aero and 3D MIMO air quality assessments models the project will effectively address the air pollution and will enable information driven decisions to be taken by public authorities, citizens and businesses
