| Zusammenfassung |
| The EU FP7 Monitoring and Assessment of Regional air quality in China using space Observations, Project Of Long-term sino-european co-Operation, MarcoPolo, project focuses on deriving emission estimates from space and their refinement by spatial downscaling and by source sector apportionment. Satellite observations of suphur dioxide, SO2, over the greater China area are analyzed using novel techniques [Fioletov et al., 2011; 2013] in order to enhance the observational signal and provide a robust SO2 dataset for the region. Observations from the SCIAMACHY/Envisat, GOME2/MetopA and OMI/Aura missions are assessed in this work and their relative strengths and shortcomings discussed at length. Rigorous screening is applied to and presented for each data source, including a full length spatiotemporal statistical analysis. Furthermore, identification of point sources such as power plants and urban agglomerations, as well as the definition of their relative contribution to the general SO2 levels, form the basis of this investigation. |
