Satellite and Local Measurements Based Services for Air Quality Improvement

AIRBUS presents a global monitoring service on atmospheric composition and emission allocation. Air composition and meteorological data from satellites and local sensors are combined into a chemical transport model to build up or validate trace gas and particulate matter emission sources and their impact on air quality. The service is using the AIRBUS’ developed OMI and TROPOMI satellite sensors to be able to quickly disclose new regions around the globe at low cost, as has been done for eastern Asia and the Indian continent. This yields a database of up-to-date emission sources at a spatial resolution of about 3.5 km (and in the future 1 km) and provides daily observation data on regional and transboundary transport of pollutants. Target constituents are NO2, particulate matter, CH4, (tropospheric) ozone and SO2. The full blown service adds data from several measurement systems (on ground, aircraft, high-altitude solar powered drones or pseudo satelites (HAPS) and nanosatellites) and various data like land-use and traffic information to achieve street level spatial resolution while maintaining accuracy and validation status. The resulting database of emission sources has the same street level spatial resolution and is intended to serve local issues. It has presently been built for several EU cities. This advanced and cost-competitive Air Quality Monitoring service is used for awareness building, policy development and policy evaluation and enforcement. The intent is to realize a commercial global service, based on local cooperation. The paper will describe the service and status.
