The aim is to develop an integrated information system for monitoring and forecasting tropospheric pollutants over China. The system uses satellite andin situ air quality measurements and modelling to generate consistent air quality information over China. The data will cover the recent years and the actual situation including an air quality forecast for several days ahead. Air pollutants covered are ozone, nitrogen dioxide, sulphur dioxide, formaldehyde, carbon monoxide, methane and aerosol/particulate matter.
The proposed system will supplement and broaden the existing ground-level monitoring and air quality assessment activities in China. Satellite data cover regions where no ground-based stations are available; air quality models fill-in the sparse temporal and spatial sampling of the measurements and connect them in a physically consistent manner.
The system targets environmental agencies in China, some of whom are participating in AMFIC, and assists them in their reporting duties on air quality. A case study for the city of Shenyang will be demonstrated. The project will also improve our understanding of the transport of air pollution within, from and to China.
