13. Some advantages of AMFIC web data base: By breaking huge global files to many gridded ascii files we make the process of those data easier for users interested in specific spots.By breaking huge global files to many gridded ascii files we make the process of those data easier for users interested in specific spots.

14. A case study on the use of Methane data 3. Analysis * The XCH 4 SCIAMACHY data appearing on the 4 figures have been scaled by 1.02 as discussed in Schneising et al., 2009

15. A case study on the use of Methane data 3. Analysis 1.The good agreement between the satellite and ground observations is probably due to the high altitude of the station. 2. According to Xiong et al., 2009 the (August-September) AIRS peak is connected to methane transport to the upper troposphere from the monsoon-Tibetan anticyclone system. 3. According to Xiong et al., 2009 the decrease of AIRS vmr thereafter is connected to the withdrawal of the monsoon and the dissipation of the Tibetan anticyclone. 4.The good agreement between SCIAMACHY and AIRS observations could be indicative of the transport of methane to the upper troposphere.

18. 3. Automatic Plume Detection: Within the AMFIC data base demonstration of image analysis techniques for automatic plume detection Three-step procedure: 1.Reconstruct the missing parts of maps (images), which lack information due to the daily coverage stripes of several satellite instruments or due to cloudiness, albedo characteristics etc, with the use of Cellular Automata (CA). 2.Extract only the regions on the map which are covered by significant plumes with the use of a cut-off filter. 3.Calculation of the area covered from each plume. Matlab image analysis algorithm runs off-line, integration not feasible Matlab image analysis algorithm runs off-line, integration not feasible

19. Cellular Automaton approach: A cellular automaton requires: 1.a regular lattice of cells covering a portion of a four dims space 2.a set of variables C attached to each cell giving its local state at the time t=0, 1, 2, … 3.a rule R={R 1,R 2,…,R m } which specifies the time evolution of the states in the following way: where designate the cells belonging to a given neighbor- hood of cell where designate the cells belonging to a given neighbor- hood of cell In our case each cell is represented by an image pixel The rule R applied here is the extraction of the average from pixels in the neighborhood (Moore neighborhood ) that contain information

26. 3. Work status Objectives The objective of this WP is to exploit the outcome of the WP2, WP3, WP4 and WP5, to determine the applicability of satellite observations for studying and monitoring transport of air pollutants. It is to demonstrate how to use data from satellites to explore processes relevant to the transport of air pollution and to monitor these processes. It is also to integrate this ability with the GEOSS, INSPIRE and GMES requirements. Finally, to provide an extensive system assessment report, suitable for feeding GEOSS and GMES requirements, as well as an assessment of options and operational requirements for long-term operation of such a satellite system. For the achievement of these goals, data will be homogenized and made available in a web database, and a workshop will be organized where all potential end-users will be invited and will interact with the project partners.  Accomplished

27. 3. Work status Description of work Task 6.1: The different data fields, observed, modelled and/or assimilated (NO2, ozone, SO2, HCHO, CO, CH4, aerosol) will be homogenised and brought into a common spatial and temporal format, complying with INSPIRE requirements. At the project website, a web database will host these data. Underlying the database structure, a set of tools will allow easy manipulation and analysis of the data, more specifically: Automatic detection of features such as plumes and monitoring of their evolution, Cluster analysis Data co-variance analysis, enabling the detection of emission signatures of different sources Export of data in different formats  Accomplished
