The major works of this project are improving the information security of sever of air quality monitoring center, reinforcing the process of system data of air quality, replenishing the database in content, to consolidate the functions of air quality monitoring network, data security , data processing and data completeness. 　　To avoid the internet users access data from the EMC server directly, may result in the danger of information security, this plan build up information announcement with isolation data of EMC database server, and design a complete system for information announcement, to carry air quality information synchronicity on both nets of inside and outside in secure way. Besides, on user’s management, via strengthen user’s login security management, increase auditing efficacy, redesign the authority of management system, to resolve the more and more complex demand of authority management. 　　For assessing the applicability of new generation air quality index (AQI) in Taiwan, add the calculation and report function for AQI. That could calculate the AQI by hour, date and area, to compile various statistics, and set up all sorts of AQI related report. 　　In order to provide topical subject of this system, devise a new vision effects style to display environmental protection concept on the air website. To improve the user operation, we redesign menu operation, single window query form , three input selectors and newly trend chart to make user easily to use. 　　Other related monitoring stations data are also integrate to the portal; include the UVI monitor data, international present air quality data, Modis- satellite remote survey, microwave temperature profile system, photochemical assessment monitoring stations, MPLNET systems, Lulin mountain background site and supersite. 　　Regarding to the requirement of data process of weather monitor items, included wind direction, wind speed, the temperature, rainfall, rain strong, UVB, UVA, we redesign the new test and verify program of data processing, data schema store planning, periodical computing assignment, and link with original computing operation, design the data schema, generate all necessary and special computation batch to provide air quality forecast work in regularly. 　　The work to enrich the air quality data could divide into three dimensions: The first, analyzes the archived data of PDP 11 system, which collected air quality data from 19 stations of 16 items , from 1982 to 1993, then transform the data format and insert into EMC system row by row, the imported data could be query and report in EMC system which made the EMC air quality would originate to 1982. The second is to import the calibration data from the first generation air quality database. That include the history calibration data from 1993 September to 2004, users could make a comparison with the air quality history data for reference. The third is to processing the data of mobile stations. The monitor data of mobile stations contain coordinates data attributes. After integrate the mobile station data from middle server, through the GIS service in EPA, system could show the weather station and the air quality station near the mobile station in the map.
